Graphics driver failure followed by unbootable system
Hi
Windows 10 has been installed on my old Toshiba Tecra laptop for some weeks now and running fine.
Last night the machine rebooted, I think after a MS Office 365 update.
The whole drive is encrypted with Truecrypt. I was able to get back in and found the intel graphics adapter had been identified as a Microsoft Basic Graphics Adapter (with resulting incorrect resolution setting) and the monitor profile had been lost.
I eventually sorted the graphics adapter issue by running windows update and reinstalling the intel driver. I also installed the .inf file for my monitor so that this was correctly identified in device manager.
All seemed ok.
The this morning I found the machine had again rebooted during the night. The machine ran through a reset procedure up until rebooting when it gave the 'UNMOUNTABLE_BOOT_VOLUME' message.
I have tried the truecrypt rescue disc but I think I have the incorrect one with me, but I don't think Truecrypt is the issue here as the bootloader indicates the correct password has been entered by displaying the 'booting' message.
So am stuck and wondering if anyone can shed any light.
UPDATE
Should have added that I enter the Truecrypt boot password and the machine indicates that this is correct as it declares 'booting'.
Then preparing system repair with options to Troubleshoot or Turn off your PC. Choosing Troubleshoot gives options to Reset this PC or advanced options. Reset PC originally ran into 'unbootable system drive' message. On 3rd attempt just now, got a series of other options including one to repair system drive. Eventual outcome is that 'StartUp Repair could not repair your PC.
I am trying to work out of this is a Windows Update issue, a hardware issue (failing hard drive or somesuch,), a truecrypt issue, some combination of all these or something else.
Will see if I have the updated truecrypt rescue disc created after I clean installed windows 10. But can't do that until Tuesday.
Thanks in advance for any pointers and advice.
