Having Problems installing Windows in my new desktop

Recommended Posts

Hi, I hope this is the right place to say this.

I got a new desktop a few months ago and i am very pleased with it and all the hardware works but i do have a question

I am having a very strange issue that despite by best efforts i am unable to solve.

I am having trouble installing Windows 10 or 11 onto my fairly new desktop pc.

The computer has 3x 256GB PCS 2.5" SSD's
I use Linux as my primary operating system so that is loaded on one ssd and boots first.

I have been trying to install Windows on the other ssd but no success - every time i come close to installing it has an error that comes up.

The closest i have come to finishing the installation is when the Windows setup says "Finishing up" then i get the error which is usually "Windows could not prepare the computer to boot into the phase of the installation"

All the drives are good with no errors and formatted correctly and the windows media tool downloaded without any issues.

I have disconnected all my non essential usb's and in my BIOS i have allowed "Windows UEFI" only to boot, it was the only setting under "Secure Boot" which says i need to disable but there is no specific option for that.
It just says two things:
1) Windows UEFI
2) Other OS

I am trying to install windows so i chose option 1

Really not sure what the problem is. The computer runs perfectly with no issues at all but will not allow me to install Windows

Hope somebody can help

neither be installed nor started. Most current Linux distributions include a signed boot loader or kernel and the system can also be installed and started with activated Secure Boot. However, there are always problems. › Linux and Windows in parallel a computer – it works, we tell how to do it. (Photo: IDG) basics 70 › Linux and Windows parallel on the PC Sometimes, for example, the boot entry is not transferred to the firmware memory ("NVRAM"). You should therefore at least install Secure Boot in the Disable Uefi firmware setup. It's different on every PC. An instruction for this should be found in the manual of the motherboard or the notebook.

Or try to use a helping software.




Hope that works. Good Luck!

Windows can only be installed on the first drive, on the primary controller, not anywhere else.
So, if Linux is taking up what "would" be seen as drive C, that's your problem, install on the primary drive, install Linux on secondary drive, and see if it will boot 🙂
