Cannot Boot Windows 7 Professional Without DVD
Nov 2, 2009
I purchased Windows 7 Professional 64-bit (as a student) and created an ISO, then burned it onto a DVD. I installed Windows 7 Pro on a system previously running Windows Vista Home Premium 32-bit.
I had no problems until this past Sunday. At first, I had a "BOOTMGR is missing" error. Since I had "custom" installed Windows 7 on the same hard drive I had Vista on without formatting the drive, I thought that formatting the drive and reinstalling Windows 7 would solve the problem, but it has not.
My current boot error provides the following information:
File: BootBCD
Status: 0xc0000034
Info: The Windows Boot Configuration Data file is missing required information.
I've read several posts with solutions for problems similar to this and most have suggested first trying to have the Windows 7 install disc try to identfy boot problems. I have done this and experienced an interesting problem.
When it scans the drive for boot errors, none are found, but I noticed it says my Windows installation is on the D: drive, but when I am actually logged into Windows 7, the installation is on the C: drive. In addition, I have also tried a suggestion to use command prompt and fix the BCD (bootrec /RebuildBCD), but it still has not changed anything.
I am really clueless where to proceed from here. I have held off from reinstalling anything onto my system in case any solutions presented require me to reformat or lose any of my applications/settings.
The only other thing I can think of that is potentially causing this error is that my secondary hard drive (B:) is listed as Disk 0 under Disk Management, while the drive with my Windows 7 installation (C:) is listed as Disk 1.

Any time I boot Windows 7 Professional on my laptop it does not start the first time. I get only a blinking cursor on black screen.
I need to switch it off and re-boot it then it starts perfectly. It does that all the times.

despite the fact that i have been trying to boot up win7pro64 in normal mode in my vaio for the past one month, all of my endeavors have failed so far. i am left with nothing else other than going for recovery resulting the loss of all of software (hopefully, i can backup my data by using ubuntu which is present as dual-boot and/or by safe mode which are booting fortunately). i have tried the following so far in safe mode:
# HDD/RAM tests; passed
# malware check by malwarebytes; passed
# reinstalling the graphics driver as i have a doubt that the video driver is not working since screen goes blank instead of getting blue logon screen with user name/icon/password after windows initial boot (the cursor appears on the screen and i can make it move by using touchpad); passed
# start-up repair; failed
# going back to last good config; failed
# restore point; none exists!
# manual update by downloading recent patches from windows update catalog (using a different computer as this did not allow for some weird reason) since the problem started only after recent windows update that failed during installation; failed.safe mode does not allow me to fix anything, windows update does not work here in addition to some other important functions that could be done in normal mode.couple of windows updates and loss of the system? i will absolutely hate to go for the recovery.

My toshiba c650 laptop recently acquired a virus and now it will not boot. I was running windows 7 home premium 64bit at the time with ubuntu 11.10( I think) my computer crashed while I was running a mcafee scan and has not booted since ubuntu also does not boot due to the windows 7 system failure. Any way I was wondering if I bought a windows professional 64bit upgrade, could I Install it from boot? I also need to know if it would wipe all virus's from the hard drive. It would be best to mention that I have tried safe mode, safe mode with networking, my recovery discs and a blue screen repair discs all that happens when running these is a black screen with white cursor I left them all for an hour to see if anything happens but sadly nothing does.

I have checked my DELL Latitude 6500 laptop running WinXP Pro using the Windows 7 upgrade advisor tool, and everythihng is a go. I also know that I need to do a good backup of my critical files and the pictures I want to keep.I have had many people tell me that before I make such a change in operating systems, do a backup first, because Windows 7 requires a clean startup, because there is no upgrade from XP to Win7.Is there an easy way to keep these work related files, and .jpg pictures using a simpler backup process than the software backup program called Acronis?I have also read that there is a program that will run at the same time as Windows 7, like a separate operating system called XP Mode. As I understand it, XP mode runs in a separate window on the Windows 7 desktop, much like a program, except it's a fully functional version of Windows XP. In Windows XP Mode, I think you can also access your computer's CD/DVD drive, install programs, save files, and perform other tasks as if you were using a computer running Windows XP.I am not sure Acronis can be installed on this DELL Out-of-Warranty Win XP laptop, if I am currently using it for my desktop with Win 7 Ultimate. Once the critical files and .jpg photos are saved on an external hard drive, can I bring them back onto the laptop on the same harddrive with the new operating system Win 7 files, or do I need to partition the laptop harddrive, or does it matter if I use them with Win XP Mode?

I tried to do a Repair Install following this tutorial, but the Compatibility Report says:"Windows 7 Professional cannot be upgraded to Windows 7 Professional. You can choose to install a new copy of Windows 7 Professional instead, but this is different from an upgrade, and does not keep your files, settings, and programs. You'll need to reinstall any programs using the original installation discs or files. To save your files before installing Windows, back them up to an external location such as a CD, DVD, or external hard drive. To install a new copy of Windows 7 Professional, click the Back button in the upper left-hand corner, and select "Custom (advanced)"." I have Win 7 SP1, but only a Win 7 disc without SP1.

I have a self built PC running XP Pro SP3, and I'm planning to upgrade this to Windows 7 Professional, initially dual booting until I've sorted out all hardware & driver problems.The hardware is an ASUS M3A78-CM motherboard which I know supports 64 bits architecture, 2 x 1Mb DDR2 800 MHz DIMMS and an AMD Athlon II x2 250 Processor @ 3GHz AM3 CPU which, I understand, also has 64-bit instructions.
To the nitty-gritty, given that I can easily buy more RAM as required - there are still 2 free slots on the motherboard),should I go for 32-bit or jump to 64-bit. Will my existing software (including Office 2010, Acronis Disk Director and True Image, Steganos Suite etc) install and reap the benefit, or will I need further expense to upgrade all these.And how much RAM should I buy if I stick with 32 bit or if I jump to 64 bit.

I built this computer Dec 11, and have had consistant installer issues from day one. Installing or removing programs hangs/takes forever or doesn't work at all. I don't get any error messages. It just hangs forever. Sometimes, if I go to bed on it, it will be complete in the morning. On the first Windows OS install, once I got the install probs, I just did another clean install. It didn't change a thing.Sometimes, thru the past, I've just ignored the errors, and simply tried to get along without some of the programs I've wanted to install. But now, Windows Updates aren't installing either, and the persistant messages and restart prompts are driving me crazy.Where in the heck do I start? I've run Microsoft's fixit for install errors.

Everytime I try to open up a program, a window pops up and says "Access to %1 has been restricted by your Administrator by policy rule %2.". What does this mean, and how can I deal with this? I am an Administrator already, and I am using Windows 7 Professional.

I have an HP G71 laptop, and I want to re-install Windows 7 on it. However, I have a few issues with simply re-installing on it.1.) The product key. Like many people, I have an official license sticker on my computer. The problem is the product key is completely faded and unreadable. But unfortunately, that's only the least of my problems. The key on my laptop is for Windows 7 Home Premium OEM, and I need at least Windows 7 Professional for work. The upgrade key I have for Windows 7 Professional has already been used, so it's not genuine to use again.2.) OEM software. I've never had to re-install Windows 7 on this laptop, so it's still loaded with the 'wonderful' OEM software that was pre-installed on it (some of it I can't even uninstall). My laptop does have a recovery manager on it, but if I were to do that, I would still have all the unwanted OEM garbage on it. That's why I would rather do a clean installation with a key that is not OEM, rather than use the recovery manager.I'm not exactly in any boat to go out and buy a new key, but unfortunately that is seeming to be my only option as of now. Is there any way I can obtain a key for Windows 7 Professional for free

I just bought a Dell XPS 8300 that came with Windows7 Home Premium. There is a chance I will need to upgrade to Professional. Is there any issues upgrading from a Dell loaded version of Windows? I have the reinstall disc that came with the PC.Side note... if I were to upgrade to Professional, and then some point down the line have to reformat my drive, would I be able to use my Dell disc with Home Premium and then use my upgrade to Professional again? Or would I have to buy it again?

I built my computer a few weeks ago and my friend had a copy of Windows 7 he was able to give me (he got it through this tech class in high school, it was a website they had, I don't remember what it was called). Turns out though, that after I installed the OS the key that the website gave was incorrect. I tried a few keygen finders (Magic Jelly Bean, KeyFinder, etc.) and they came out with a different key than what the website gave me, but still didn't work. I tried to activate over the phone and the lady on the line told me I installed the upgrade or something and I would have to buy the full version. I've came to the point where I'm just going to buy the OEM version and install it. My question is will installing the oem version over my current version of win7 screw up anything? Would all of my files be in the same places? Or is there anything I can do to avoid the registration period all together so I can save 90 bucks?
