Here's a random question for everyone. To start, this has already been resolved and I'm looking for reasons to why.. Google doesn't quite have this one and I can't stop being perplexed by the unknown.
1) The computer's hard drive was just DBAN'd from a disk, using the same disk that attempted to install.
2) Used a bootable WinPro x86/x64 (attempted both) from a multiboot USB --- Apparently old tech (HP dc5000) can't handle Win7 from USB.. Hardware not supported error.
3) Used a bootable x64 and newly made x86 DVD that had been verified in other computers --- hangs on black screen with an underscore upper right, then something about no bootable drive (continuously tried to rollover to blank HDD when booting from DVD).
4) I had a computer with working parts, working disk drive(s) (swapped with others) that was registered by the BIOS.
5) Used the x86 install disc with the HDD in another computer and it installed fine.
6) Using the same hardware, I'm able to boot to an OS from another HDD and the DVD drive still registered and could be read from the OS.
So what possibilities could cause a computer to fail to boot from a disk that's verified with tech that's verified, then boot to OS and act like nothing happened?
The two things I can think of as possible causes are the 3 blown/bulging capacitors (yep.. nothing less than perfection), and random happenstance that ancient technology (and modern) likes to give IT professionals.
If you've ever had this happen, I'd like to hear your story, if you have an idea I'd be interested in finding why.
