THANK YOU!!!! I Made an account just to tell you how thankful I am for your tip!!!! I was running into a much more modern issue with Windows 10. I was going from a RAID to a new SSD. After multiple blue screens, I fugred it had to do something with the bios settings. Windows basically just needed to recognize it.

Thank you again my friend :)

Sorry for the bump. I didn't want to start a new thread. In my BIOS there are two options where I can change IDE to AHCI. One of them is a RAID setting and the other is, damn, I forget, integrated peripherals or something? Anyway, would I just change the latter to AHCI and leave the RAID setting alone since I don't use a RAID array?

I tried another method where you change values in the registry, changed my BIOS settings and booted and got a blue screen every time. Thankfully you can reset and get into your BIOS and put your settings back to IDE and Windows will boot fine again even with the reg values changed.

Man, it's Vietnam all over again.

Okay, this method worked when the registry method did not. Thank you!

Okay, weird, now my SSD is showing as ejectable media? How do I fix this?

Last thing, it didn't boot originally when I did this but went back into the BIOS and noticed it changed my main boot drive. So if this happens to you double check that the boot drive didn't change. Sorry about all of this message spam. Thanks again!

The exact same thing happened to me, mine boots with no error messages or beeps, no flashing errors too help identify what's wrong. B it just runs with absolutely no display of any kind. I've tried everything I can think of. Reset CMOS, swapped ram, different monitor and cables. Nothing, the worst part is not seeing a darn thing to help the diagnosis out in any way. Any one got any ideas? I'm all ears, thanks.

Very Respectfully, MJ

Hello everybody. What started out as a request for guidance ended up with me solving my own problem. Thought I may as well pass on my findings anyway just in case it helps somebody else in the same situation.

So over the weekend, through a series of upgrades, I successfully hopped from Vista to Windows 10 Professional 64-bit. But, as is not unusual, I again managed to snatch defeat from the jaws of victory. With my new SSD loaded with Win 10 goodness, I realised I was still operating it in IDE mode. A confident dip into the BIOS to enable AHCI mode resulted in Windows then failing to start because it no longer recognised the boot drive! I'm guessing the AHCI driver wasn't loaded during installation since the mode wasn't in use. So back to IDE mode and a surf around for solutions. Plenty around pertaining to Vista, Win 7 and Win 8 involving changing registry values but nothing tangible for Win 10. However I found this alternative Win 8 workaround which I can confirm works equally well in Windows 10. I realise I'm probably teaching my Grandmother to suck eggs with this post here but perhaps somebody as equally technophobic as me, may find it useful. This is what I did:

1. Run Command Prompt as Admin
2. Invoke a Safe Mode boot with the command: bcdedit /set {current} safeboot minimal
3. Restart the PC and enter your BIOS during bootup.
4. Change from IDE to AHCI mode then Save & Exit.
5. Windows 10 will launch in Safe Mode.
6. Right click the Window icon and select to run the Command Prompt in Admin mode from among the various options.
7. Cancel Safe Mode booting with the command: bcdedit /deletevalue {current} safeboot
8. Restart your PC once more and this time it will boot up normally but with AHCI mode activated.

Asus ROG, worked for me as well after searching for solutions for hours.
