How do I boot my Lenovo laptop?

I have a Lenovo Thinkpad Edge. Yesterday I was copying files to a harddrive and then it was stuck and I could not do anything, so I force shutdowned it.

Everytime I put it on, I get an option of "Startup Repair" and "Normal Startup".

When I choose normal startup, it takes me to a blue screen saying that there was a problem and that I must choose " Startup Repair" and then it restarts. It will repeat this loop each time I choose "Normal Startup".

When I choose " Startup Repair", the screen goed black for 1-2 minutes and then I get to the blue screen with green and white leaves and only my cursor will show which I can move. It will stay forever like that if I don't force shutdown it.

So restart it and when the lenovo logo screen appears( first screen that appears when you power on the laptop), I can press Shift+F1 to go to BIOS options, but there isn't anything there that I know of that can fix the problem.

I googled and they said I must start it with Safe Mode which is Shift + F8. When I do that, I get a message that says Error 0210 Stuck Key 42 (or 2a, it depends) Press F1 for startup. When I press F1, nothing happens. It is the same at the BIOS options. I can't press any F key exept ESC and ENTER, but Shift+F1 works when I want to get to BIOS options.

What on earth must I do to make it work without losing my data?

Depending on which Windows OS, you might try the "Repair Install" of only Windows files from either the hidden partition of factory original stuff, or a Windows OS disk set or a flash drive. You can download bootable ones.
This ONLY does Windows files. No personal files or settings are changed. But if successful restarting, you must do OS updates, probably driver updates.

It sounds like your hard drive has errors, and so does your filing system. You should not have to use Shift + F1. That sounds like a bios setting for having f-keys switched at startup.Eg numlock/keypad options. You need to get to safe mode command prompt you can do that by BOOTING a CLEAN OS CD. At the prompt you must repair the drive, usually a chkdsk/f is good enough. You might also need an sfc/scannow from command prompt, but only after chkdsk has fully passed. After that you should be able to boot, but it also sounds like a better drive diagnostics is called for.It depends on the make of the drive.Either seatools or hitachi dft should be ok to use to do a in depth disk sector test(non destructive)

Try removing the ram start up in f8 repair my computer use system restore to go back a couple days before you copied the boot sector virus to your computer
