Dual Boot - Lost The Option To Boot Into XP
Nov 24, 2009
When my computer wouldn't turn on in the morning I did the usual diagnostics; unplug things one at time test with spare components etc... Any way I qucikly figured out the PSU was dead so I ordered a new one and was back up and running. However when I reassembled the computer after unplugging everything (and removing the m/b) I plugged the HDDs back into different SATA ports from which they orginally came. When I came to boot the computer up I got the error message: 'BOOTMGR missing' or it may have been 'NTLDR missing' I can't remember.
I fixed this problem by using the 7 startup repair utility. I have no problem booting into Windows 7, but I have lost the option to boot into my XP install on anther disk. I looked in the boot tab under System Configuration and the only OS showing is this Windows 7 install. So my question is this: how can I get the choice of which OS to boot back?
(I should mention that the XP install is on a different disk from the 7 install).

I created a separate partiton and installed Win 7 fine. It dual booted fine as well. I then renamed the old XP boot partition and this caused the PC to give NTLDR missing and wouldnt boot.
So I reinstalled Win 7 as a custom install and it all boots fine into Win 7 without providing me a dual boot option. I am not too concerned about this as eventually I was going to go completely over to Win 7 anyway
Question I have is
1) The old Win XP boot partition is viewable in explorer. Can I just reformat this and reclaim the space - I want to make sure that the PC is not looking for any files in that old partition
2) Can I delete the Windows.old folder as well

The problem I'm having is that I had been running WinXP SP3, I used GParted to partition my hdd so I could do a clean install and try out windows 7. The odd thing is though, at first when it would boot up I'd have two option to select from, either "Windows 7" or "Select an older version of windows", then I reinstalled windows 7 at one point(to the same partition used before) and lost that menu all together, now whenever I turn my PC on it just acts like windows 7 is the only OS installed.
I know my other partition is still there though, my question is, how would I go about retrieving it if possible. Can I just pop in my WinXP disc and do a repair or recovery on the other partition? Never had this problem dual booting windows and linux so im unsure as to what I should do.

I've installed 64bit win 7 on a 2nd partion of my main drive running vista 64bit. The installation all went smoothly and loaded into win 7.
But when restarted I did't get a windows boot manager screen so i could pick if I wish to load Vista or Windows 7, instead my system just loads straight into Vista.
Do I have to enable my system to be able to see the Windows 7 install?

Ok, i have windows 7 already installed fine on my 2x raptor raided drives, i decided to install xp 32 on a new partition on the 2x raided raptors, after using nlite to integrate my raid drivers into the new xp iso (no floppy) it installed fine on the new partition.
However, i saw no boot menu on reboot and every time xp would load by default with f8 showing no other OS to boot. I then ran the windows 7 64 dvd and attempted a repair of startup option, it failed 5 times in a row quoting a corrupt boot sector.
I was all ready to give up when suddenly it just repaired it after the 6th attempt, i did nothing different but it said to reboot so i did and to my incredible relief my win 7 install started booting again.
But again, no boot menu and this time the xp boot has been lost! Is there any way i can manually add something to get a dual boot function running?

I have lost the ability to dual boot after installing windows XP.
I Originally had windows XP. I partitioned the drive in order to install windows 7. Installed windows 7 fine, no problems, was able to dual boot. After getting data from XP partition. I decided to do a clean install of xp. After doing that my machine only boots into XP, I no longer have the dual boot option.
I have tried booting off the windows 7 dvd and 'repair computer'. It said it found some problems and fixed them. Rebooted, still only booted into XP. Tried booting off DVD again ran 'Startup Repair option' Again, said it fixed some things, still only boots into XP.
I also tried EasyBCD and it said it fixed the problems, but everything is still the same. I can only boot into windows xp. No dual boot.
My boot.ini, ntldr and ntdetect are all on partition that has windows 7 installed.
Saw the posts about Vistabootpro but wanted to make sure i went that route before i purchased it and wanted to make sure of the correct steps to follow.

So I just got my hands on Windows 7 and wanted to play around with it, and everything works but:
Previous Computer Setup:
I had a dual boot with XP and Vista that worked perfectly (both OS's were on separate HD's and worked / booted correctly.)
Drive C: --------> Vista (Now Windows 7)
Drive D: --------> Windows XP
Problem:
After upgrading my Vista to Windows 7 (Via clean install) I lost my boot menu to choose XP. Now everytime I flip the power it boots DIRECTLY into Windows 7.
How do I recover my boot screen option so I can boot back into XP when I need to?

I just installed windows 7 ultimate on my pc.
i already had xp32 and vista 64 business on a dual boot on the same HDD before installing windows 7.
during windows 7 install, I selected the xp32 partition, formatted it and installed windows 7 over the top as I no longer wanted xp32.
When the windows 7 install was complete I expected to see a dual boot screen with
option 1. windows 7
and option 2. vista64
unfortunatelty i have no dual boot options, the pc now just goes straight into windows 7. It doesnt sem to know that vista is there.
i would appreciate assistance in getting a dual boot set up with vista64 and windows 7

I had Windows 7 and Xubuntu set up in dual boot by EasyBCD, a well known utility.Today the linux kernel has been updated and, after the following reboot, the choice of Xubuntu OS at the dual boot prompt didn't work.So I went through Windows, launched EasyBCD to fix things and:
- changed the order the entries (Win 7 up, first)
- selected Windows 7 as default OS
- removed Xubuntu entry
- added again Xubuntu entry through EasyBCD procedure
- saved (maybe I should have saved after each of the changes)
When I rebooted I've found that two identical Xubuntu entries, each pointing to the Linux OS, and no Win 7.I've tried to access Win 7 by Grub, but it points to the dual boot screen, so I'm at start point again.I don't have the Win 7 disk but the usual recovery partition. No backup. Going through the recovery partition gets me back to the dual boot screen..Is there any way to put it in order again? Could you suggestions work in this case?I know that, from Linux, I can install and overwrite MBR with free mbr.bin
sudo apt-get install syslinux
sudo dd if=/usr/lib/syslinux/mbr.bin of=/dev/sda
But I'm not sure it will give me back Windows 7.

I have messed up my dual boot of XP Pro and Seven
Seven was working well, but XP was playing up.
I did a restore from an earlier acronis image of XP.
XP now works again, but as you have guessed I have lost the dual boot menu to select Windows 7 when I bootup.
I know boot.ini does not apply with Seven.
Please tell me how to get my neatly tweaked Seven back on the boot menu,

I lost access to my windows 7 drive (Dual-boot windows 7 & Ubuntu). every time I try to run Windows 7 I get the message: Bootmgr is compressed, Press CTRL_ALT-DEL to restart. I could run Bootrec /fixmbr or diskpart or attrib to rebuild my mbr table through DOS command window using my windows 7 recovery CD. The problem I cannot access drive C: where my windows 7 are. I get the error message: Cannot open volume for direct access or system cannot find the drive path or specified. I still can access all my windows folders and files through home folder in Ubuntu. I don't want to reformat and reinstall windows. Is there is a way to run the DOS commands within Ubuntu

I have XP (x86) installed on one partition.
Last night I installed Windows 7 (x64) on a separate partition.
Anytime I had tried this in the past, using Vista, it always detected the Windows XP partition, and gave me a boot menu with "Earlier Version of Windows" option to boot to.
This is not so with Windows 7.
How can I get the boot menu to show both options, to boot to XP or to Windows 7?

I installed opensuse 12.1 on dual boot along with my other windows 7 installation. Installation of opensuse is successful and i can use it. But when I tried to use windows 7 on grub, it says bootmgr is missing. I've already encountered this problem a long time ago so i tried to use bootrec /fixmbr, bootrec /rebuildbcd and bootrec /fixboot in the recovery console in the windows 7 DVD. Rebuildbcd and fixboot did not work and it said something like it cannot find my windows installation. I also tried bootrec /scanos, it returned a windows installation on D:\Windows but my windows is in drive C. I think this has something to do with me messing up the active partition in disk management a month ago but i already fixed it by setting the active partition to the system reserved partition. Only fixmbr is successful, but now i can't boot on any OS because it says: Missing operating system.I also tried bcdboot C:\Windows but it failed with a message that goes like: Failure when attempting to copy boot information..

I can't get Win 7 to boot after setting up dual boot (Ubuntu 10.10) on my GF's laptop. I'll describe the problem and everything that has been tried so far. REALLY hoping somebody has an idea, I'm getting desperate.I installed Ubuntu last night via the Live CD. Used the Live version to install alongside Windows and partition the drive, install Grub, etc. At reboot, after POST it would just go to a black screen with a flashing cursor. I could only run off the live CD. A forum member determined the Grub was trying to load from the wrong partition. We changed that and voila! Grub now loads properly. I can boot into Ubunto via Grub with zero problems. HOWEVER: when I try to boot into Win 7 from Grub, it just locks at the same flashing cursor of death screen. The 7 partition is till intact, I can see and access all the files on the 7 partition from within Ubuntu, however 7 will not boot. I have tried downloading and burning the Win 7 repair disk and doing all of the following,Running the automatic Start Up Repair - several times. All it does is remove Grub, but booting still goes to the flashing cursor and I have to reinstall Grub again to be able to do anything after POST.I have used the command prompt to run "bootsect /nt60 SYS /mbr". Has the same effect as above.I have used all the bootsec.exe /fixmbr, /fixboot, and /rebuildBCD commands. Again, all have the same effect and I have to reinstall Grub to get anywhere.I don't have an installation disk to try and just do a repair install because Asus apparently doesn't feel that I would need one of these. All I have is the recovery disks from the Asus AIRecovery application that want to just re-format the entire drive and start over. This isn't an option. It's my GF's laptop (mine gave up the ghost last week) and we both have WAY too much highly important data on here. Not to mention she would castrate me . Now from all my research the only other thing I've come across that sounds possible is that the boot flag needs to be set to a different partition. Somebody had a somewhat similar problem and it turned out the way Dell set up the system the boot flag had to be moved to a recovery partition and it worked fine. I'm wondering if Asus has something similar going on, but I can't figure out how to move the boot flag. I'm going on 12 straight hours of working on this now

I setup an XP/Windows 7 dual boot on two drives. Currently C: Windows 7, D:XP
Love Windows 7 and now I'm ready to convert to single boot Windows 7.
I'm not real savy re. bcdedit so will need very detailed instructions
I did find the command line in Windows 7 by going through accessories but I'm scared to go further without help.
Eventually I want to clean up the D:xp and use it for storage etc.
I'm guessing this procedure may have already be written up but I can't seem to find it.

How to Change the OS Name in Windows Boot Manager ?

I recently added a hard drive to my computer (SSD), and installed Windows 7 x64 onto it. The result being a dual boot system, which by default boots to the SSD, and optionally (by Windows Boot Menu), can be booted to the original drive (standard mechanical drive).
Initial setup went fine, however I decided to customize the Windows Boot Menu, so that logical names could be associated with each operating system instance. To do this I used EasyBCD and I altered the names in the Windows Boot Menu from: Quote:
Windows 7
Windows 7
to... Quote:
Windows 7 - SSD
Windows 7 - Standard Drive
Shortly after the modification I noticed that I was no longer able to boot into the original OS. Instead I was being presented with a "Repair Windows" option. Figuring that my EasyBCD "tampering" may have had something to do with the issue I decided to change the names back to "Windows 7" in the Windows Boot Menu. However doing so had no positive impact on boot up of the original OS.
After booting again into the original OS I accepted the "Repair Windows" option, and then left the computer over night to do it's "thing". After completion of the "Repair" the situation has deteriorated -
* Windows doesn't load (the same as before)
* Windows doesn't present a "Repair Windows" option (it did before)
* The computer reboots a short period after the "Starting Windows" screen is presented
As a side note the drive is in good health, and all data on it can be read from within Windows 7 when I boot to the SSD OS.

I have a laptop I bought a year ago on which a created a dual boot Win 7 (32bit)/Win XP SP3 install, each on a separate partition. It was my first Win 7/XP dual boot install, and my first personal system that I allowed to have a Win 7 install on it at all, so although I have plenty of experience working on pretty much every previous version of Windows, I have very little experience with Win 7 and dual boot configs.
Today about 2 hours ago my audio spontaneously stopped worked for no good reason, so after shutting down each program to see if that cured it (which it didn't), I restarted the system. Out of the blue, for the first time I've ever experienced it, I received the msg "MBR Error 1" - Press any key to boot from floppy. I don't have a floppy of course on my laptop, and if I press any key I simply get the same msg. I turned the system off for a few minutes to make sure it was a good cold boot, but every time I still get the same msg. I tried switching the BIOS setting from IDE to AHCI (IDE is required for XP to boot, AHCI required for Win 7), but I still get the same error msg before I'm even prompted with the OS boot selection, so it made no difference of course.
I looked up this issue and found various suggestions, but none of the ones I found took into consideration a dual boot config., they were all Win 7 specific solutions. I don't what to try and repair the MBR only to have it screw up my dual boot config and be unable to access XP, which is what I use almost exclusively, nor do i want to lose access to Win 7 if at all possible.
I had a backup HD of my complete system that I saved several months ago when I upgraded my HD, and I periodically refresh the most important files on it, so I'm currently running on the laptop in question using my old HD, and it's working just fine. Worst case I can just clone my old HD to my newer HD that's screwed up, but I'll still lose a lot of changes I've made to the OS since I upgraded the HD and have to reinstall and config a number of programs, so that's my last option. I'll also have to back up about 200GB of data from the newer HD which is much larger than my old HD, and then restore it back after the clone, something that will take a lot of time and unncessary effort if I can just fix the MBR.

I'm having a problem every time I power on the system. I'm dual booting vista ultimate with win 7 build 7100; with vista I have no problem, but with 7 every time I start the system the first boot attempt gives me the error 0xc000000e after the boot manager display: "the boot selection failed because a required device is inaccessible".;after a reset the system boots 7 with no problems. Win 7 is installed in a brand new hd(seagate barracuda 1.5tb) and vista on a second hd.
I've search the web for people with a similar problem with no success. I've tryed already many solutions but the problem persists(latest bios for the motherboard, latest intel sata drivers, etc). I'm hoping that this could be a bug in win 7 instead of a hardware failure for the hd. Again, the strange thing is that this only happen after the power on. After that first error, no matter how many reboots, the system always boot without problems.
