Its a Vista Acer laptop over a year and half old. It started acting slow, then one day when it comes to turning it on it comes up with the bootmgr missing error message. Now I looked around and tried the disk repair solution. When it came to the repair it said it couldn't. I tried the "bootfix" after that and restarted to check results. It came up with a black screen with a flashing cursor. Now it won't even boot the cd no matter what boot order it has and no devices plugged in. Help!
