Long time follower, first time posting! For once I am stumped!
A friend came to me with the error "The boot selection failed because a required device is inaccessible.". I have spent about 20 hours trying to fix it, but unsuccessful. Here is (was) the setup.
Two 1 TB hard drives, in Raid 1 (mirroring). I say "was the setup" because I inadvertently pulled the cable off one one drive, so when I booted up the BIOS said "Raid was in critical condition". To my understanding (which is limited when it comes to RAID), in a mirrored setup, if one drive fails, the other one still works. So I have been working with only one drive trying to get the the computer to boot to Windows 7.
Things I have tried (on the RAID 1 setup, and each individual drive):
Ultimate Boot CD: (Only tried this when both drives were in RAID 1). The disk allowed me to repair the boot record, and when I rebooted it said "Missing Operating System".
Windows Repair Disk. When both drives are plugged in Windows see's 2 different windows installations. I try to repair #1 and it fails, when I try to repair #2, it fails. The reason, "Missing OS Loader".
CHKDSK: Everything came back ok.
Bootrec .FixMBR: Said it was successful.
Bootsec /nt60 SYS c: (Dont remember the exact input but there was a great article I followed). This also was successful.
I am not sure what else to do. My only option at the moment is to re-install windows on one drive and save the files from the other drive.
I hope that you guys can help me get the RAID 1 set back up and Windows booting, with out a total systems failure.
Thank you for your time and any suggestions.
