What is Unsurmountable boot volume?

Unmountable boot volume error blue screen?

  • I have a toshiba satellite a665 laptop running on windows 7 64 bit. It was working fine earlier but after trying to restart it got stuck on the windows screen and then comes the blue screen that say unmountable boot volume. I tried running it on safe mode but it gets stuck on the avgidseh.sys. I thought there was something wrong with my hard drive so i took it out and plugged it into another laptop. I booted it to the boot to last successful boot or something like that and I was able to start up like normal. I deleted all the avg programs, ran malwarebytes and it came up with no errors. I then restarted and tried to boot it on safe mode and this time it got stuck on classpnp.sys. I've been trying to resolve this problem for hours without any resolution. I can still log in by using the last successful boot option only on my older laptop and not my new one. I thought it would be a problem with my hard drive but it works on my old laptop but just not on my new one so I'm guessing that can't be the problem. Any help would be greatly appreciated because I am going crazy. Thanks in advance.

try bassman's suggestion. press f8 to bring the boot options. if it's not f8 then try other f keys there should be an option "boot with last known good configuration". try it if still no luck then you need to format. take out your hard drive, put it in another machine, copy your files to it then format your hard drive
