I have bought my laptop in 2011, when Microsoft Windows 7 was latest desktop Windows OS.
Today, Windows 7 is dead. There is no reason of installing it for four months.
I have attempted to install Windows 8.1 and 10.
Windows 10 USB didn't support EFI because of incorrect partitioning.
Windows 8.1 stuck in reboot loop with installation error message, so I had to use legacy boot.
When installed with legacy boot, both Windows 8.1 and 10 had screen shaking issue (but I forgot to install drivers, because they are labeled 'for Windows 7'). SD card reader didn't work.
I have installed Windows 7. It works in EFI mode (but bootloader needs to be fixed from installation media), but it needs Wi‐Fi drivers found on DVD‐ROM. IIRC SD card reader worked in Windows 7, but this time it asked me to format SD card, which I didn't do.
On GNU/Linux, SD card reader is working better than on Windows 10, but still cannot read SD cards. I don't know how to install bootloader correctly, because when boot entry is created, system reboots, so it is installed to fallback path.
What should I do?
