2. choose your language settings, then click Next
3. Click "repair your computer"

If I put in my Vista disc then it comes up with another screen asking If I want to run in Safe mode, run normally etc.

My keyboard won’t work on this screen so I can’t select anything!! What do I do? I really don’t want to have all my stuff wiped so please help…
I would try to do that but my keyboard won’t respond when the screen comes up, so I can’t select anything.

my aunt asked me to install Windows Vista Home Premium on her comp.,she had XP and it saysWindows Vista capable.When Installing I selected the Upgrade option instead of doing the clean installation. no problems installing,but afterwards everything is running slow. Ibrought the comp.to my house to use dsl &installed all the the windows updates in hopes that it would solve the slowness. When that was done the computer restarted itself &said it was configuring the updates & then when I came back to check on it Windows Boot Manager was on the screen saying:
"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1.Insert you Windows installation disc and restart your computer.
2. Choose your language settings, and then click NEXT
3. Click REPAIR YOUR COMPUTER
…File: \windows\system32\winload.exe status: 0xc000000f

When i put the vista or the hp reinstall disc in nothing happens. PLEASE help I really dont want to lose everthing. THANKS.
I can’t get past the Windows Boot Manager, I tried pressing F8 to try and get it back to last known good configuration, but pressing F8 doesn’t do anything. I’d be happy if I could just get back to the XP version so she doesn’t lose any of her programs, and then trying to re-install Vista while connected to the internet.

Hello there I have a Toshiba Satellite laptop running on a upgrade from windows XP to Windows Vista Premminum. I have been running this version for some time now and nothing has happend in which I can not fix myself.. I have recently come accross a problume that brings me up to Windows Boot Manager. I will read exactly what it says and how it says it.

Windows Boot Manager
Windows faild to start. A recent hardware of software change might be the cause. To fix the problume:

1. Insert your windows installation disk and restart your computer.
2. Choose your language settings, and then click "next"
3. Click "Repair your computer."

If you do not have this disk, Contact your system administrator or computer manufacturer for assistance.
File: \windows\SYSTEM32\Drivers\SSHRMD.SYS

Status: 0xc0000098

Info: Windows failed to load because a critical system driver is missing or corrupt.

Thats when it ends. Now I know it tells me how to fix it but I have a problume.. When it tells me a critical system driver is missing or corrupt… dosn’t that mean its hardware failure or something like that and even if I put the disk in if im having hardware failure it wont work…

Also im concerned with what might have caused this problume. I know before the crash. I had gone onto Trend Micro 2008 anti viruse and it said a few things about windows changes and said that they were high so I changed them back. So im thinking when I changed them thats what happend… I know I might not be making a whole lot of sence but yeah im kinda confussed I have never seen this before….

So guys if you can help me out I will offer alot of points for it and if it is possable to instant message me at Musiclvrkd
