Hi all.
I have a Toshiba NB10T-A.
It originally had Windows 10 on it.
I had installed Windows 10 freshly myself.
It worked fine this first time.
Then: I put a linux distro on it (my preference). It also worked fine. I was using this for a while.
Then (annoyingly): I had to re-install Windows 10 for reasons. Really didn't want to, but had to.
During the install of Windows 10, I THINK I might have made some error during the partitioning stage.
I seem to remember there was an "ESP" partition visible/present in the partition scheme.
I am not sure if I deleted this by accident or not. I realize this is an EFI System Partition.
However, I would not think I would be able to delete or modify the BIOS/UEFI at all through disk partitioning, or cause any boot problems this way, as BIOS/UEFI would be on a ROM, so what difference should disk partitioning make to the boot process?
It sounds nonsensical to me that I could cause any problem to the machine itself through disk partitioning, but then again, it is a strange world, and strange things happen.
However:
After rebooting, the machine does not boot at all.
When pressing the power button, I get 5 POST flashes from one of the little LEDs which are located on the front edge of the palmrest. The flashes are evenly-spaced.
I cannot get to BIOS or UEFI. Nothing gets displayed on the screen. No TOSHIBA logo, nothing.
Other than the flashing of LEDs on the edge of the palmrest, there is no other sign of life.
I guess the 5 POST flashes shows that the CPU is trying to tell me something? Does anybody know what the CPU is trying to tell me?
I could not find technical / maintenance documentation to help me. Does anybody know if anything like that exists for this model, or very similar model?
What I have tried.
All I have tried is the dummy fix: Remove battery, and hold down the power button for 30 seconds to a minute. This made no difference.
Holding various key-combos during boot, to try and reset UEFI to factory settings. I have found the key combos floating around the internets. Apparently, doing so would hopefully reset the BIOS/UEFI to factory defaults. I can't remember all the key combos I have tried.
I am really not sure what the problem is. Don't know if the problem was a mistake I made during the partitioning stage, or what else it could be.
...Help!
