dual boot - self-changing unit letters

On a pc with xp on C partition and Vista on E partition, when booting from
the latter it gets the S letter, thus giving me troubles when accessing user
accounts.
Which could be the workaround?
Would a repair install fix it?

thx alot, ric

 

Hi,

First, there is no repair install function in Vista. You'd basically have to
reinstall to the same volume, and the old installation would be moved to a
windows.old folder. If it originally installed as S:, then there is no
reason that the drive letter should affect the user accounts. Did you
attempt to alter the drive letter via XP?

 

Thanks, the original letter was E when booting from XP or Vista as well.
I have tried changing letter from XP, but using bcedit I have seen that S:
was kept in.
Luckily I could enter safe mode and install easybcd which fixed my problem.
(I had to go through task manager, no other working way to run commands).
