Can I change D: to C: or should I just leave it.
Windows 7 install disc shows my disk as C:
saying here that you should change it or should not change it..
Rather, posting some random thoughts and questions.
Before actually doing anything, the disk image backup advice is an absolute must.
The OP should only have "Disk_0,Partition_1" IAW his posting.
The D: should just be a letter.
The 'registry' seems to be the main concern about this.
Note: this is not for others who have more than 1 partition, OP only,
since he did the actual deletion/merging: Is this letter ( D: ), in fact, carried through your current 'registry'?
Can the OP be 100% sure about this? Can you post a pic?
(Can a registry search be done to prove/disprove this?)
If his registry is carrying 'D:\' for items, how can the OS find them? What mechanism is used here
Windows 7 says he is C: which should be 'Disk0_Partition_1',
all programs should now be on 'Disk0_Partition_1',
and the registry has pointers to D: ???
Somehow, this doesn't seem to jive right, to me.
It strikes me that if the OperatingSystem's "Disk Management" or "diskpart" allows OP to change the D: to C: (which it may or may not allow),
then the OperatingSystem should have the 'brains' to change all Registry-entries containing D:, to the new letter C: .
I thought that's what OSs are supposedly for, to keep track of things...
I believe that the letter D: is just that -- a letter.
Running 'diskpart' from the Windows 7 booted DVD should confirm that. Could you post a list of your "diskpart" output results?
If there is a "D:" it should be the DVD drive.
If the OP Registry does have ( D: ) in it, then its more screwy than I could have ever imagined.
OTOH, I don't know a bloody thing about the Registry, that's why all the bloody dumb questions...
