Windows 7: Changing drivers letters without access to Admin tools

Changing drivers letters without access to Admin tools

In my last topic, I needed help fixing a boot problem. This is a follow up.

Upon logging in, I realized that my computer could not find any of the contents of ProgramData, Program Files, Program Files (x86), or Users. I had all of those folders symlinked because of my ssd boot drive configuration. Whenever I removed my old data partition (from before I got my ssd) it changed around the drive letters and now Windows 7 cannot seem to find all of my stuff. Unfortunately, due to this problem, I cannot access administration tools and thus cannot change drive letters. Is there any way I can change drive letters? I can also not access command prompt from inside the installation. I can still access all of my installed programs by going to the Program Files folder where they are stored. Is there any third party program that can do this?

EDIT: Here is a bit more information: For those of you who might have trouble understanding how I have things setup: I have pretty much everything except the C:\Windows folder symlinked to my HDD. I did this so that my computer doesn't have to do nearly as much writing the the SSD (SSD's are not very good that that) and to free up space in case Linux or OS X ever start supporting trim and I want to put a boot partition for them on it.

I doubt it'll work, but you can change drive letters via Partition Wizard

BTW, Make sure your user account has full adminstrative priviledges (Although you may not be able to change that )

Ok I installed partition editor to a thumbdrive on another computer and then inserted it. It will run, but I cannot change it to G:, the letter that it was before. Is there any way to fix this?

EDIT: Wait, I think I found the problem. that is because the thumb drive I inserted is letter G. I'll fix that first

EDIT 2: OK, now that that is done, I need to boot with the recovery disk and remake the symlinks back to G:

This is an unusual setup you have for your system. You became victim of the "SSD write paranoia". many people think it is bad to write to an SSD where in fact it makes no difference one way or another. All you get with your setup is a performance degradation. I would put the whole system back on the SSD.

As far as your drive letter dilemma goes, did you try Disk Management. You may have to move a few other letters around first in order to free up G.

There will have to be some symlinking either way. It is only a 30GB ssd and I have a 1TB HDD. Also, isn't disk management part of admin tools? No I could not access disk management.

But a 30GB SSD is ample for the OS. My Win7 is at 17GB after running for 5 months and a lot of programs installed. I deleted the hibernation file but kept the page file.
If you cannot get to Disk Management, then Partition Wizard is your next best bet. I just used it yesterday. It seems to do a good job.

I'm also waiting for Linux and OS X to support Trim, at which time I will create boot partitions for them in a tripleboot-hackintosh setup. Also, most smaller SSD's have subpar write speeds. I have put my paging file on my HDD as well.

Changing Drive Letters
I have installed Win 7 on a SSD on C:. My two HDD were assigned different drive letters other than what I would like. Is it safe to change the HDD drive letters in Drive Management without messing up my data? Thanks,

Is it normal when installing Windows 7 that it installs itself on 'C' Drive and moves XP from 'C' Drive to 'D' Drive even though it appeared to be installing on 'D' during installation?
