Windows7 wont boot

[kamikaze702]

Ok so I am working on a PC for a friend. I start it up and the first error I see is that the Boot Manager is missing. So I restart the PC and boot from the recovery sector. I tried to use the Startup Repair from there and no luck. I try system restore and no luck. So I go into the command prompt and run check disk, repair, and a couple others. Didn't work.

So finally I made a Win7 recovery/repair DVD from another PC. I go in to BIOS and set the boot order to boot from the DVD drive first. So it starts up and the DVD drive starts reading the disk and all I get is a black screen with a flashing cursor in the top left corner.

While running the repair tool from the hard drive after it failed these errors showed up.
Problem Signature 5 AutoFailover
Problem Signature 7 CorruptVolume

Any info would be great, Im bleeding from my ears from banging my head against the wall.

Could it be malware? http://www.bleepingcomputer.com/for...to-start-system-repair-cant-discover-problem/

Instead of doing all that crap I would burn Bitdefender live CD and scan the system. Make sure the computer has an Internet connection. http://download.bitdefender.com/rescue_cd/

It's the ISO file and you must have more than 512 MB of RAM. IMGburn portable will burn the disk.

So then if its malware, should I just reformat and and do a fresh install of Win7?

That's another option I guess, but if you have important files I would try a virus scanner. I would wait for others to respond before you format and see what they say.

It gives me two options to boot up with, one being to start windows normal, and the second says start in Recovery mode. No option for Safe Mode shown.

On bootup pressing/holding the F8 key should give you the safe mode option. Did you try it that way?

Ok when I hit the F8 I get a black screen that says to hit any key to boot from CD or DVD. I hit enter and received this message "The file is possibly corrupt. The file header checksum does not match the computed checksum".

If I don't hit any key when prompted it just goes back to BOOTMNGR is missing.

get the dvd out of the tray.

get the dvd out of the tray.

No disc in tray, when pressing F8 I get "This version supports only Hard Disk and CDROM drives" please wait. This will take a few seconds. Then it goes to black screen with a flashing cursor in top left corner.

ermm..Go into startup revery or whatever
after it tries..exit out and double back to get a command prompt
..then type:
bootrec.exe /fixboot
enter
bootrec.exe /fixmbr
enter
bootrec.exe /rebuildbcd
enter

If that doesn't work..grab whatever's important and wipe it.
