Here is the situation. My customer called me and said his computer keeps booting in an endless loop. I suspected a corrupted master boot record. I went to his house, booted up into the Recovery Console, did memory checks and such, and did a FIXBOOT command. Well, this did nothing for me except give me some typing practice. I noticed too that I can't get it to boot into SAFE MODE.
When I rebooted it, it came up with the infamous "NTLDR IS MISSING - PRESS CTRL-ALT-DEL TO RESTART". And then it gets really exciting!! I tried rebooting again and got the BSOD 0x0000007f error. Well, I did all of the normal processes of elimination by removing one RAM module at a time (but memory already checked good so it was more of a second check than anything else) and disconnected one CD/DVD drive, although since I worked on the hard drive last, it just makes sense that something went awry on the hard drive.
Moving right along, I removed the hard drive and connected it to my Linux laptop (gotta love Linux!!!) and Linux sees all of the folders and files. I think something got messed up in the boot sector but now all I can get is a constant BSOD. Let me just clarify one point I left out above....the BSOD appears when I try to boot from the Windows XP disc in an attempt to get back into the Recovery Console. I think that perhaps the FIXBOOT and FIXMBR commands jacked up some pointers and now the processor doesn't know where to look so it stops.
I say all that to ask this: Is there a way I can take advantage of being able to access the hard drive via Linux to make it bootable again? As I said, I think I jacked up some pointers somehow and Windoze isn't letting me in. If I boot WITHOUT the CD, it just says DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.
One other point: During boot, it shows no IDE Channel 1 Master (which is where it should be seeing this hard drive). So, in effect, it doesn't even see the drive.
So, I can't boot up into the Recovery Console and I can't get to a command prompt in any way. I've tried two separate system disks and every time it gets all the way through the loading of drivers and such for setup and then it goes to BSOD 0x0000007f.
I can easily enough get all of the data off the drive through Linux but would love to restore the drive to functional without having to format it. Any ideas??
