I have an Acer Aspire 5920G laptop. I was also told that the issue is likely my hard drive, but I DID replace my hard drive and the same problem happens.
It was freezing and acting up so I decided to do ANOTHER factory restore with my set of discs I purchased from Acer. This has always seemed to work in the past, but this time... I get to disc 3 (at 100%) and it comes up with an error message that says, "Restore failed - reason 0xd000000a. Click OK to restart the computer". So, when I do restart the computer, it says, "BOOTMGR MISSING Press CTRL+ALT+DEL to restart".
