BSOD bootup & safe mode win7 0x000000ED error unmountable boot volume
Hope someone can help me out. I have a acer e525 Win7
im getting this error on the bsod - UNMOUNTABLE_BOOT_VOLUME
some text then STOP: 0x000000ED (0xFFFFFA800270ECD0, 0xFFFFFFFFC0000185, 0X000000000000000000, 0X0000000000000000)
When i boot up it bsods and in safe mode too (tried all options in advanced settings either bsod's or hangs). \Windows\system32\drivers\CLASSPNP.SYS. is where the boot up fails. I tried to run from windowsrecovery disc but it becomes idle after trying to run recovery. I opened up the laptop and disconnected the bios battery (it was password protected, I don't remember ever password protecting it - possible virus?) then after an hour soldered it back. Put it back together checking all connections and dusting it off. The bios is now accessible. I ran memtest off a flash drive and uncovered no errors. I ran chkdsk from command prompt on the windows recovery disc. I've attached a pic of the results. I tried to get memory dump info for you. I set the debuginfotype to 1 for complete memory dump.
If i have left something out please let me know,
Thanks
