Windows 7: Changing boot drive letters in Windows 7?

Changing boot drive letters in Windows 7?

Vista Ultimate 64bit / Windows 7 Ultimate RC1 64bit

I successfully installed Windows 7 on a blank drive. The installation kept the drive letter "H" and name.

Drive C: Is my Vista boot drive, and I'm done with it. My plan is to change it to some higher letter of the alphabet, then . . . .

Question I
If I change my "G" drive (Windows 7 boot drive) letter to "C" with 'Disk Management' will all be well?

Question II
Will just deleting my Vista installation cause any problems with the Windows 7 installation?

Thanks for the help, palms are sweating :-) - IM

1. are you changing your drive letter in Windows 7? or vista?
2. it shouldnt, if your currently dualbooting Windows 7 and vista, and you delete vista, the mbr will still boot Windows 7 correctly. Also keep in mind, if you format the vista drive, and its the first partition, youll have a blank partition, thne Windows 7 partition.

The Sly Assassin - I will change the drive letter from H: to C: using Windows 7 'Disk Management'. Windows 7 is on it's own unpartitioned drive.

The C: drive is one large volume and I'll use it for something else after deleting Vista.

Sound good? Thanks, IM

In regards to number 2, With Vista being on 'Drive C', wiping it will also probably wipe the bootloader I think. You need to figure out where that is first. I dont know if it can be moved personnally because I've never tried it.

Just a heads-up before you try it! (if bootloader gets wiped, system wont boot.)

hmm, im not sure if thats going to work,Windows 7 should set the main drive as C: automatically. Just the MBR im worried about, because if you change the drive letter, the MBR will look where your Windows 7 was, not where it changed to.TBH i'm not entirely sure mate. look think you might have to take a stab in the dark, change it and hope it works.
