I installed Pop! _OS on my PC via USB stick.
Now I need Windows on my PC for a project, so I created a Windows USB stick on my laptop and instead of the PC booting directly into the Windows setup as always, it now boots in GNU GRUB 2.04.
That is as far as there's a problem with none of my keyboards working, I have to watch how the time runs out, can't select an option and then it boots to Linux as usual.
The problem now is that I can't get into my BIOS (DEL) or my boot menu. If I try that, I end up in GNU GRUB where I have no way to install Windows.
Does anyone know a solution for this?
Your PC has exactly one USB port, where the keyboard also works in the BIOS. Check if you can find it. Had the problem before and simply didn't come to the bios until I tried all the USB ports.
One of the USB ports is the default input port, which is loaded and activated by the mainboard BEFORE the BIOS. Sometimes noticeable when the Num Lock light comes on before anything can be seen on the screen.
I can't even get into the BIOS.
That means I have to try out all ports until I find the one that works in GRUB and then I can go from Grub to the bios?
Worked. Got into the BIOS on another port. Thank you!
(And absolute garbage whoever came up with the idea to solve it like this)
To add:
With various mainboards, USB HIDs only work on older USB interfaces (i.e., use USB 2.0 port if 2.0 and 3.0 are available). The same applies sometimes to USB boot.
Ultimately depends on the age of the board and the firmware. It gets really bad with keyboards that do not support the HID boot protocol.
Really bad in older systems: If the USB legacy function in the BIOS is inactive, a PS / 2 keyboard is absolutely necessary for the BIOS.
No, it has nothing to do with grub. As soon as grub has been called, the possibility of entering the BIOS is over.
The advice, if you have a USB keyboard to try on other ports, is quite good.
The BIOS has only a limited program memory, if your USB keyboard is also switched on via a HUP, it may be Not served.
So take a port that is mounted directly on the motherboard.
An operating system can afford to support all possible hardware. If all of this doesn't fit on a DVD (like the many drivers for Windows), then you may Directed to the manufacturer's site.
The BIOS only has a ROM with very limited capacity. That leaves only a small selection.
It is a good idea to use USB at all. Years ago, only PS / 2 keyboards could be operated.
The bad thing is that such information is not even in the board manual or in such a way that it can't be found.
A good solution is to install a different hard drive and a different operating system, e.g. Windows to install. So the unfree Windows has no adverse effect on the initial installation. Linux no longer starts when Windows is installed afterwards - unless Supergrub2 is within reach.
It is worth keeping the hard drive from old laptops.
