I have a 3 years old Dell XPS 8700 (SSD 256, HD 3TO, 32G Ram, Intel I7) shipped with Windows 8 and subsequently upgraded with Windows 10. I have recently installed Ubutuntu 17.04 which seemed to work properly.
Today My computer froze and I tried to reboot it. Though Once in grub, whether I choose Windows or Ubuntu I get a blackscreen.
I tried to log from a USB stick with a version of Ubuntu 16.04. I selected "try Ubuntu" but then again black screen.
From the grub I tried "check disk errors" but failure again. Dell Bios diagnostics show no problem. (Though I suspect something is faulty somewhere or maybe SSD is dead or some corrupted data) Also I tried to Boot directly into Windows from the Bios and bypass Grub, which gave me Windows Recovery (though I have never made a recovery disk) and cannot go further here.
My concern at the moment would be to retrieve some files on SSD disk which holds the Windows partition. The best would be to boot Ubuntu from a USB disk and migrate important files to HD before attempting things on the SSD ? Otherwise should I just remove the SSD and recover through an USB3 adapter ?
And then maybe wipe it and try to reinstall Ubuntu (my Windows is OEM so no install disk at hand and I don't mind having Ubuntu only)
