So, a few days ago my computer wouldn't exit sleep mode despite my efforts. I had to force a shut down. Upon restarting, it proceeded to BSOD while at the "Starting Windows" screen. Next screen included "No hard disk is detected". Successive attempts to restart did not reach the former but went straight to the latter (The hard disk message is really the only reason I'm posting here). However, it appears to me I simply can't boot from that hard drive with Windows 7. I am currently using Knoppix from USB. Thing is, I'm not sure if this is a hardware issue or a problem with Windows 7.
So here's the status so far:
1. Running Knoppix from USB, the hard drive in question is listed & accessible. All recent data I hadn't backed up on an external drive is now backed up.
2. The data on the hard drive is not corrupted (copied most of it to an external drive & tested it with a different computer). I can also save new data on it.
3. The hard drive in question is not showing signs of disrepair (clicking noises, etc).
4. Normal startup includes displaying options from the motherboard (BIOS setup, boot menu, etc) as always. Now it momentarily displays "Loading Asus Express Gate..." before this screen. Just a change I noted; idk if it's related.
So in your opinion, is this a hardware or software problem? I suspect it's the latter, but I normally don't trust myself 100% with computer issues.
