1. Hard Drives. How many hard disk drives are attached to the system? Did you keep them as "basic" disks or did you change them to "dynamic"?
2. Partitions. How is each drive partitioned? Primary partition(s), extended partitions, logical volumes within extended partition, something else? Which primary partition is set "active"?
3. Windows 7 Boot Loader. Did you make any effort to remove the Windows 7 boot loader or attempt to restore the Windows XP boot loader?
4. Recovery Console. Is this the Windows XP recovery console? And at some point you installed it to the hard drive?
Oh boy.
Where to begin...
Some of the things you've asked, I'm not even sure what they mean/are.
1. 2 hard disks, C:/ and D:/, C: is Windows and D: is some kind of HP recovery console that was pre-installed on the machine. I never switched anything with the disks, that I know of. So I imagine that they'd just be "basic" discs.
2. I know that C:/ was the primary partition, then I accidentally switched it to something on one of my D:/ -- In the RC, there are 3 options for me to log on to:
1) C:\Windows
2) D:\iniNT
3) D:\I386
What I did was switch the primary to either 2 or 3, now cannot seem to get it back to 1, despite using the commands. It says that I've switched it back when I type certain commands (fixboot, fixmbr), but when I reboot my computer, nothing has changed, i.e., only RC will load.
3. Did not make any attempt to do anything with the boot loaders, although, my original intention was to go back to XP; but, in regards to what you're asking, no. I did not remove or restore any boot loaders.
4. This is Windows Recovery Console, and I did not install it to the hard drive myself. It must have come preloaded like that.
