boot error

[pegasis]

I have a laptop that I experiment with.

I took a laptop HD and installed it and put linux on it.

now I removed that HD and installed the original laptop HD with win 8.1 in it.

but when it boots up I get a grub prompt, saying partition error, entering rescue mode, grub rescue

what does this mean, and how can I get this laptop to boot and see the
windows 8.1 drive again

grub is the bootloader for linux, but I don't understand why you're having an error since you used a discreet hd for the install. Do you have any flash media installed, and if so, could you have put grub on that?

I have no flash media installed.
this is kinda strange

where is Grub, in the BIOS?
the linux drive is gone (out of computer)

I thought UEFI fixed this, and any drive would boot up

why can't any discrete HD with an OS just boot up
this is huge pain

and what happens when I get windows to load, is this something that happens
every time I boot this laptop with this drive?

what happens when I put the Linux drive back intot he laptop?

I am not understanding why this is ahppening

I don't understand why you're having problems, but perhaps I don't sufficiently understand modern computers. grub should be in the mbr of the hd(legacy), or in an efi partition of the hd(modern). Go back to the old hd, and it should be like nothing changed. I don't know where grub is on your system, but if you put the linux drive back, I suspect it'll boot.

I have the old HD with the original OS (win 8.1) installed but I still get the grub loader
no such partition error?

I am confused as you are
makes no sense
why would it be in the EFI?

I need windows on my laptop now, not linux

Not the same as I understand it. That install was made with two drives in the computer at the same time. In that case, there can be problems with bootloaders being overwritten. In your case, only one drive was in the comouter at any time, so there should have been no problem.

in this case I set the bios to defaults and UEFI was it, and the BIOS tried to boot, but drive was not working.

I installed another drive and windows booted up fine

will be interesting to see what happens when i put the Linux drive back in

linux needs CSM boot set, not UEFI

who knew
