Have a blissful day!
I have a Hp g62 windows 7 64 bit laptop that recently when I turn on I get the following message: status: 0xc000000f. info: the boot selection failed because a required device is inaccessible. I have made a USB windows 7 repair disk but the problem with that is it never loads past the language input screen even after hours, but has worked a couple times to where I could use the command prompt. When I use the command prompt to fix the MBR it did not work. Has anyone experienced this and if so how to fix it?
