A few years ago I noted to make and keep a bootable OS that we NEVER LEARN to deal with such problems. Read http://tips.oncomputers.info/archives2004/0401/2004-Jan-11.htm and use a more current version like Mint or another.
THERE IS NO REASON TO LEARN THAT OS. WE ALSO DON'T INSTALL IT.
These other OSes don't honor Windows Security and that's a good thing.
I have an HP laptop running Windows 8.1. I tried to enter safe mode yesterday and the screen just went blank. Since then i cant do anything. When i try to start the computer, it tries to go into the diagnostic mode but then the screen just turns blue and it locks. I tried a recovery disk and it does the same thing. I pressed esc on start up and got to the menu and tried the recovery partition and still nothing.
There is a file on this drive that i desperately need. I even removed the hard drive and tried to read it on another computer and it shows as unallocated space in disk manager. Im wondering if this is because of the windows security.
Im thinking the drive didnt fail because the bios on the original computer sees the two partitions.
Any ideas anyone?
