Windows 7 / Mac OS X Dual Boot - Endless Loop
Nov 16, 2010
How To: Dual Boot Mac OS X Snow Leopard and Windows 7 on a PC. Now I have the usb stick all set up perfectly and I know it works because it begins to boot. unfortunately it does begin and says Darwin for a split second but then it resets to the HP logo and restarts again. I am able to switch the directory to boot from so my Windows 7 side is unaffected. But I cannot get the OSX side to start. I have been able before I choose the boot site to have on the bottom like a command prompt it seems like where it just says BOOT: and I can type what ever I like into it.

I 'got' windows 7 home premium 64 bit edition, went through the install, got to completing installation, then just as it finished it told me some error involving it being unable to do something with a certain piece of system hardware. I don't remember the exact message.Now it's just restarting and telling me that windows failed to install, and that I should press ok to restart.

I have had Windows 7 64bit Pro on my computer for around 10 months. I use an Upgrade version through my University that works exactly like a normal copy of Windows 7. I have had no problems with it until now. When I start it up normally and choose Windows 7 (I also have Windows XP pro on my computer) and after about 10 seconds my computer automatically restarts. I tried the Repair My Computer option 3 times and the Last Known Good Configuration twice with no success. When I start it up in Safe Mode, 7 works for about three seconds and then goes to a Blue Screen before restarting.I honestly do not know what is wrong with my computer. I have checked all of the internal connections and there doesn't appear to be anything unplugged or messed up with them in general.

Recently, I was on my computer (A Toshiba Satellite L305D-S5974. Approx 2.5 years old) when it started to shut down with the famous blue error screen. As annoying as this was, it wasn't a big deal. No, the big deal started when my computer started acting up. It took longer and longer for it to boot to the desktop, sometimes even a half hour because I had to keep manually turning it off in on in order to get a response. Now my computer won't even go past the "Starting Windows" screen.

I was recently using my girlfriends computer when a message came up saying something about an automatic update then went into a repair mode. Then when the computer restarted it went into startup repair. It says it can't find any problems, and when you restart it, it keeps going to startup repair. The computer originally had XP on it, and her step dad installed 7 right before we moved across the country, so we don't have any kind of install or recovery discs

After a (sloppily done on my part) multiple driver update on 7 Home Premium x64, I've been tossed into Startup Repair. SR goes into an endless repeating loop - never reporting failure, just an endless repeat. I've used the Windows 7 install disk and tried System Restore. Twice System Restore has reported success, yet I immediately end up booting back into the Startup Repair loop.
I am given no options - when I try F8 I'm simply tossed back into Startup Repair. I'm thinking there may be a command prompt way out of the loop, but I'm clueless in that area.

my work machine started acting up yesterday. even though i have it set to log in automatically, the log in screen started appearing suddenly when i boot. the only option is my regular account.
when i click it, the monitor (old crt) clicks off and on, like it's changing resolution. it goes blank for a second, then the login screen comes back up.
it takes some messing about, restarting, and lots of clicking, but eventually it logs in and i can work. any thoughts? i'm baffled. and i'd rather not spend half the day reinstalling everything...

The issue might be on the server end. I don't know. The situation is this I have internet access and many web sites are consistently difficult to access. A good example would be Newegg.com and their pages as well as the links to their site that I click in the email they send me. The blue busy circle stay in an endless loop. I can access there site sometimes if I persistently tap F5 (refresh). While this issue is a problem with many web sites that I try to access some pull up instantly. Is there something I can do to fix this or could it be the ISP or a server issue.

So, I'm not exactly sure what I did. I was clearing up some space on my computer after using the Norton Removal Tool to get rid of this Norton trial popup that came up everytime I booted my computer. Now, after it told me to restart, it seems to be stuck in an endless boot cycle that resets itself after showing the Windows logo. I've since tried running startup repair, which freezes as it shows the progress bar for 'Windows is loading files'. Safe mode will not work, either. It just sends it back into the boot cycle. Not sure what to do at this point. My computer came pre-installed with Windows 7 Home Premium 64bit, so I don't have any startup discs.

I was trying to remove some Malware and trojans on my Grandmas computer and sort of crashed it. I was using iObit and I remember seeing something about a rootkit something or another and boot.img file and I did not remove the file as it had the boot.img file, and thats kind of an important file. Anyways after trying to restore and completely reformatting the rd drive, I've had no luck getting the computer past the Windows Splash screen without getting restart windows normally or windows repair options.

I used to think I was pretty decent at computer stuffs until a couple of days ago.I sold my old ATX mobo and replaced it with an ASRock M-ITX motherboard because I wanted a smaller system.However, I didn't really know that I had to delete the old mobo drivers before setting up a new rig. Upon pushing the power button, I am greeted with a black screen stating that W7 can't boot properly. If I press "Start Windows normally" it bootloops. Thus, I downloaded Hiren's boot cd and followed the instructions from this thread:

I've found the Fix HDD controller program, but my 500GB HDD (which stores my W7) is not recognized. It is recognized in the UEFI BIOS, but not in miniXP.

I have a windows 7 pro 64 bit HP desktop computer that will not load windows. I have tried safemode, safemode w/ networking, and last know good config. I've run startup repair both from windowsRE and an original windows 7 pro disk. I have attempted multiple system restores (non destructive) to a number of different dates. The system restores say that they work but the machine still loops.
I know it's just some small windows corruption. I would have no trouble backing up my files with a linux distribution live flash drive and restoring the OS but I REALLY don't want to do that. How can I identify and repair the problem without starting from scratch. I'm familiar with msdos cli, but don't know which commands (if any) will help. I also don't know of any live CD's/ tools that will allow me to fix this problem. My problem here is simply lack of information.

I was in the middle of reinstalling Windows 7 and the power went out. The computer Dell Inspiron 1440 is caught in a continuous loop. I have 3 options to choose from when I power up the computer:
Windows 7
Windows RollBack and
Another Windows 7.
Regardless of what option I choose (I tried all 3) it goes to a second screen where I have 2 options: Launch Start up repair or start windows normally. Regardless of which of those options I choose it goes back to the first 3 choices (Windows 7 Windows Roll setup rollback or Windows 7). I can't make any progress. I have tried booting from safe mode (F8) and it still will not boot. It blinks safe mode for a few seconds then reboots and goes through the same continuous loop.
I am trying to boot from the CD; I am using an external CD drive as the internal drive does not work properly. The boot sequence it set to the CD drive first. I have tried everything I can think of and I have been searching the internet for days and I cannot figure out how to get this system back up. I do not care if I lose everything on the drive. MI have all the discs from Dell.

I am running Windows 7 Ultimate on a HP Pavilion M9080N. About a week ago the computer went into a Startup Repair loop and Windows would not start. The message I kept on getting was "Startup Repair cannot repair this computer automatically". I performed numerous system restores back to the first restore point, but it stil went into the Startup Repair loop. One of the lines in the Repair details said "Root cause found: Boot critical file C:Windowssystem32driversatapi.sys is corrupt. and another said "Root cause found: Boot critical file C:ataport.SYS is corrupt. I tried replacing it with a good file from the Windows 7 install disc by going into command prompt and typing "copy X:WindowsSystem32Driversacpi.sys C:WindowsSystem32Driversacpi.sys" and copy X:WindowsSystem32Driversapaport.sys C:WindowsSystem32Driversapaport.sys I now get the OS restart loop without actually starting. When I restart with the Windows 7 with the install disc it continually searches for the problem and seems to fix it but when I restart it goes back to the OS restart loop without actually starting.

dual booting windows 7 home premium x64 with linux fedora 14 on dual independantly dedicated drives. i am a college student with moderate computer (windows) knowledge but am doing software development and would like to play around with some linux for a class. i have no prior experience with linux and have minimal knowledge of operation. i am currently running windows 7 and would like to keep it as my primary os. i do not wish to share media files across drives or os's, windows does that just fine as is and i dont want to get into a third drive. my current drive is a 1tb wd black caviar hdd. it is also currently 2/3rds full and the desktop is about 6 months old so i would rather not partition the drive for a dual boot. i would think that there are some other advantages for the os's operating independantly off their own drives other than if one hdd dies i should still have the other with its os still ok. i have read some topics about RAID configs with dual boot setups with dual drives like this but am not very familiar with RAID. is there a RAID config that would be beneficial in this situation? i currently do not have a RAID card. my tower internals are not very accessible and i dont like the idea of disconnecting drives depending on which os i want to operate.

A Dell Inspiron E1705, w/ 2x2gb mem, 500 gb hd, ATI Radeon x1400 vid and Win 7.There were no Dell drivers or programs and the system BIOS was ver A01. Checking the Dell website against the Service Tag, I found 22 drivers and programs specific to the computer. Most of them ran and installed under Win 7 with no trouble. The last one was the bios flash utility program to update the bios to ver A10. The bios flashed, seemed to go ok. But on system reboot, after the initial screem about resetting the memory sticks, the computer is stuck in an infinite reboot loop.It loads the initial POST screen, completes the POST, seeks for its boot device and when it finds and starts to access the installed HD it reboots. I have reset all the bios settings to factory default settings. I have pulled the system battery and "cleared the cmos", but no joy there. I have created a bootable usb flash drive with another Dell laptop, and the computer will boot from that. I have other bootable cd's, and the computer will boot from them. I can use the bootable cd's to determine that the programs they run (freeware backup programs and a copy of bart pe) can access the installed hd,and see the files there, so the installed hd is intact. But i still can't get the computer to boot from it.My first thought was to reinstall the ver A01 bios, but it would not complete the process and remained at ver .A10. I was able to flash bios A09, and then A07, etc, all the way back to ver A04. But after that I could go back no further, A02 and A01 flash utilities returned an error message. If I found some compatible mem sticks and a smaller hd, installed them, could I reflash bios ver A02 or A01? Would that do me any good? (I have 2 x 256 mg mem sticks from a dell inspiron 5100 which I upgraded to 2x1gb, and a 40 gb 2.5in hd that also came out of the 5100, so I could use those parts in the e1705 to reflash the earlier bios)

i installed LibUSB-Win32- drivers so i could use iRecovery on my iPhone,on completion of installation of LibUSB my keyboard and mouse turned off, well all of my USB was disabled. so i was forced to restart, sadly same thing, login screen no keyboard or mouse, i tried in safemode, same thing. however my keyboard works in CMOS and BIOS so i know its a OS issue. and this only happened when i installled LIBUSB, i looked it up and tried manually removing LibUSB using the Win7 setup disks command prompt. i deleted LibUSB0.sys out of Windows/Systen32/Drivers so that LibUSB wont be called upon during start up, however doing this has now meant my PC will reboot after loading Windows even in safemode, the Starting Windows screen appears. fades and riight before it goes to the login screen it restarts, Safemode too. i have no Restore points and i cannot and i mean Cannot Format this harddisk, its not backed up and i have over 400GB of data i absolutely NEED.Im so stuck its not funny i have no idea what to do to get windows booting again and without this silly LibUSB stuff! i dont have aany PS./2 Ports on my mobo either!, what can i do >? Please ive asked everywhere and no one knows what i can do except reformat.

I have windows 7 home premium 32 bit dell laptop. Lately, it takes more than 10 minutes before it boots before the windows logo appears). From there the computer works normally. I got a suggestion to check for malwares or viruses so that is what I did. I started by going to msconfig and edited the boot options to start automatically to safe mode with networking, then rebooted my system. After booting, it loaded up the initial screen of safe mode, but then it restarted by itself.
I am now stuck on this reboot loop going into safe mode, it won't even let me go back to normal mode. I went to startup repair, but it didn't find anything, so had to reboot again onto the same situation. I have searched for possible answers, and the best that I could get was to remove the safe boot options and go back to normal mode. The syntax to type was bcdedit /deletevalue {default} safe boot but it didn't work, same with bcdedit /deletevalue safe boot.
I am getting this : "An error occurred while attempting to delete the specified data element. Element not found."

I have been spending the last 2 days trying to reinstall the OS on my Area 51. I had to take out the HDD and reformat it in another PC as I was getting a boot loop that would start right after the "windows is loading files..." screen and then loop back to the Alienware boot screen. So, since then.. I put the HDD back in and unplugged all USB connections, 1394 and everything besides the keyboard and monitor. I was able to get to the OS installation screen and then at the end of the install, the PC restarted and told me that windows has encountered an error and gave me choices to restart in safe mode and on down the list, but no attempt to repair. It did ask me to put the disk back in and boot from the DVD drive, which I did, but it never goes back to the installation.
So, I then took out the battery on the motherboard and put it back (also took out the GPU and put it back in). I was then able to get back to the Windows installation screen, but after the PC had to restart, I ended up back in the same place with the Windows error and safe mode options (none of which work). So, am I looking at an issue with the MIO by chance, the MOBO battery maybe or what? I'm not sure why I'm having these issues while just trying to reinstall the OS on a clean drive.Also, could this be because I'm using 2 x 4GB RipjawsX RAM rather then the triple channel (which I am getting today)? Can I just remove the memory and try to boot without it in? Or is it possible this could be due to the MOBO battery starting to go?

I get into startup repair everytime i boot my pc which is never successful. I am definitely goin to explain it in detail but dis is basic problem nd plz dont mind typing coz m typing fast on iphone which may cause errors in typing!Yesterday,i used my pc for 7-8 hrs continuosly which is not big deal but due to it i can't figure out my action which caused problem. I kept it on for downloading at night nd when in morning i got boot screen which comes when pc is directly turned off. I did Start Windows Normally nd i got usual windows 7 loading animation for a secong nd den it started startup repair after that everytime i boot it takes me to startup repair resulting in continuos failure. I hv googled nd found many threads but none matched my exact one. Startup infinity loop didn't work. Below r given few conclusions nd obstacles-1.) i can't get into advanced boot options using F8. But i can get into recovery menu using install dvd nd view advanced options frm startup repair.
2.) System restore din't work. I mean its not successful in restoring.3.) bootrec.exe didnt work4.) imp point to be noted is my last update was on 23 dec while pc worked fine on 24 th & 25th dec means dont knw wat happened 25th night that caused this problem on 26th morning.5.) sfc/scannow says "a startup repair is left to be completed." it says to complete that first then use sfc/scannow.6.) chkdsk results in last line saying failed to transfer log......7.) i also get a report like many others about that problem signature.8.) repair install not possible coz windows can't start only.9.)i hv made a backup using cmd but is there any way without clean install?

Something similar has happened before (about half a year ago) but it got fixed when I did a system repair through command promt, until these few days...the loop came back again, sometimes it would boot like normal, at times it would get stuck or it'll go into a "checking file system" screen. It first started when I was browsing the web like usual, the comp suddenly froze and popped out a blue screen, it was too quick for me to capture it tho...In the past few days its gotten the BSOD a few times ive managed to take down a couple of the STOP codes 0x0000003D and 0x0000003B, im sure Ive gotten other ones too but i only remembered these 2.I've tried system repair & restore and command prompt but none worked...i have no idea whats wrong (hardware or software?) so im hoping someone can help me find a permanent fix if possible?
I have attached the dumb files through jcgriff2.Im using a Windows 7 Ultimate 64 bit which my friend installed for me so i could use the 4gb ram i had. It used to be Windows 7 Home Edition 32 bit.My system is about 3-4yrs old now and OS is about 2yrs old i think.

As currently configured, XP is on drive C:, Win 7 was added to drive E:, and the system is currently run as a dual boot. Attempting to boot without the XP drive present will yield a "NTLDR is missing" error very early in the boot process.
I have already tried the following:
(1) I moved the hidden Windows Boot Manager files (bootmgr as well as the associated Boot folder) from the XP drive root to the Win 7 drive root.
(2) After physically removing the XP drive, I rebooted to the Win 7 installation DVD, and used the "Repair Your Computer" option to pull up the "Recovery Tools". Then, using the command prompt utility, ...
(3) I attempted to write a new boot sector to the Windows 7 disk using the command: Bootrec /fixboot, - that yields an error though. The Bootrec /fixmbr claimed success, but ultimately did not make Win 7 drive bootable.
I had to reconnect drive C: just to boot into Win 7 again to write this. I do have files backed up, but to format and reinstall files would take many hours beyond just the time to transfer 400 GB of data, since I have dozens of purchased applications that need to be freshly reinstalled and validated as well. Basically I want my E: drive now to be my boot drive while the C: drive is reformatted and used for general storage.
Any idea how to make my Win 7 drive bootable? Do I need a partition program that is more adept at creating a viable boot sector, or is that even the problem?

Yesterday I've reinstalled windows on my laptop, the only 'problem' was that on booting, the system lets you choose between windows 7 and windows xp setup. Windows xp setup was the default choice. Now when I was done installing windows 7, I wanted to get rid of the win xp setup boot option. In my control panel, I deselected the option for the boot selection screen where you can set the time. Now my pc got stuck in some kind of boot loop where it only boots into win xp setup. I don't know how to resolve this because the only option I have on booting is entering the bios... when I press f12 it should go to boot options, but it just goes automaticly to win xp setup.

My system is stuck in a boot loop while booting in safe mode,I was updating the drivers on my video card. I used driver cleaner pro to remove my old drivers. I then used msconfig to boot in safe mode with the minimal option selected. When the computer reboots I get to the screen to type in my password for 5 seconds an the computer reboots itself.

Basically what originally happened was that I tried installing windows 7 off of my hard drive and during the "completing installation" phase the computer lost power and was shut down. Turning the computer back on iIhad a screen which said something of the likes of set up is starting. From then on I was in a infinite boot loop where it would give me a set up screen and restart. I desperately needed to backup my files which I did not bother to do so.
I used my secondary desktop running vista, plugged in my other hard drive and backed up all my files successfully. I thought I would format the disk since I was done backing up all my data and I would go right on ahead and install a fresh windows 7 via the CD. I go into bios and set the windows CD to boot and I unplug my vista hard drive and leave only the formatted 1TB HD plugged in. And now I get the "BOOTMGR is missing" error. As I have read it's due to deleting everything off the hard drive including the...bootmanager.
Now with the tools that I hold (mobo with bios access, windows 7 installation CD, another hard drive with Vista). How shall I go about getting my hard drive ready to install a fresh copy of windows 7. I have the retail cd, I have another HD with vista if needed, and I have the clean hard drive which i would wish to install windows 7. I set my bios to boot via the CD first and put in the disc and let it work it's magic, I would like to point out that it still gives me a BOOTMGR error. It asks me to press a key to load from the CD and then I get the error that I know is coming.
