I have just installed windows XP on the PC i am writing from and because i
foolishly had a camera card reader plugged in and a seperate USB hard drive
connected the installation has jumbled up the drive letter allocations.

For example what would traditionally be the C drive has the letter F.

Can i change the allocations? If so how?

Thanks in anticipation

Hi Paul,

Disconnect the drives and start over. There is no other way to change the
drive letter assigned to the system volume. You can change any other letter,
just not that one. This is a common occurence, and this is the only
solution.

It can be changed via new installation of xp.

Don't re-install just for that - you will have plenty of other reasons later on
- It can be changed through the device manager? or something like that - I did
it a while ago, and if I did it then it must be easy

You can normally change drive letter identifications, but nobody recommends
fooling with the drive/partision that OS is installed in/booting from.

As Rick said, "There is no other way to change the
drive letter assigned to the system volume.", at least for anyone other than
a true professional, i.e. not the average user.

David, judging by your own posts, I think you should refrain from offering
advice to others.

Disk Manager will not let you change the drive letter on the system drive.
Disconnect all drives and do a clean install. You must remove the existing
partition.

There is a lot of big words in there, probably a bit complicated for one
who can not follow simple instructions!

I just used the regedit local machine option, knowing it might not work, but hopefull that it would. While I lay no claim to all computer knowledge, I have built hundreds of machines, fixed thousands and loaded Windows countless times. I am now in the process of a re-install. I rolled the dice and came up snake eyes. But, hey, it was worth a shot.

No surprise really, a great deal of other registry entries must also be changed when changing the boot drive letter, I've had to do it on a live machine in the past but wouldn't recommend it unless you have sufficient skills and an appropriate tool set.
