Because of the batch cmd run? Because there is no System on DISK0 now, looking at screenie.

That is curious - normally get the message if the newer bootsector is corrupted by a prior version of windows. The bootsector code should have been completely rewritten if you just ran v5 from within XP and selected F ( your 7 drive letter ).

Maybe better to boot the 7 dvd and go to command prompt - just run the command manually - avoid any problems with the partition being inaccessible.

boot 7 dvd to the command prompt, type:

bootsect /nt60 all

press enter.

where do i find the command prompt on the dvd? all i have is the install disc....

'bootsc' is not recognized as an internal or external command, operable program or batch file.

Boot the dvd - windows loading files - select keyboard region from the dropdown, click Next.

You get a screen saying Install Now - press shift+F10 together.

That doesn't sound good.

I just ran it from the recovery options cmd promt myself and took this screenie - I assume it said it was susccessful, like this:

Name:  BOOTSECT-2010-02-17_044428 (Small).jpg
Views: 192
Size:  48.4 KB

( The reason C is locked in my screenie is because I booted the wim from the drive - I couldn't be bothered booting the dvd - you shouldn't have any locked volumes when booting from the dvd.)


The other thing you might try is running checkdisk. Tell it to fix filesystem errors .

Computer>rt click the drive and select Properties>Tools >Check Now> Tick Automatically fix filesystem errors.

Or you can do it from the command prompt on the dvd, type :

diskpart

lis vol

( get the letter of your 7 volume - it might not be F from the recovery environment - check for the size and volume label - i have used z : below- replace z: with the letter of your 7 partition )

exi

chkdsk z: /f

press enter

I'll try that, yes that is the result I got. Everything is still the same, if I boot to the 7 hard drive it gives the disk error and i can still boot 7 from the xp hard drive.
