Why can't I install Windows 10, 8.1?

Question

Windows

Hello! I have a Lenovo G50-30 laptop, I've been trying to install Windows 10, I've been fighting for a month, nothing comes out. In general, if you run the installer through Windows 7 (setup.exe), then the installation goes on, but after the first reboot, a blue screen appears and the "INACCESSABLE BOOT DEVICE" error appears, and if you start the installation via a bootable USB flash drive, then with the welcome window, I cannot enter from the keyboard, the touchpad and mouse also do not work. Tried other builds, nothing helped. What to do?

Answer 1

So, who was interested in this topic, I found a solution. I share.
First, flashing the BIOS is not worth it. It won't lead you to a solution. We go into the BIOS, reset its default settings and there, at the bottom, in the paragraph about optimization for the system (or something like that), we set "Other". After we reboot from the USB flash drive and install Windows 8/10. Also, if your system is not installed due to an incorrect disk format, in the installation window press the key combination Shift + F10, in the console that opens, write (ALL DATA WILL BE ERASED FROM THE DISK!) :
diskpart
listdisk
selectdisk X (X is your disk number)
convert mbr
after the end of the procedure - exit
That's all.

Answer 2

You may need to change the bios disk mode from IDE to AHCI.

put the original distribution and not the assembly. and on assemblies for advice to the authors of the assemblies

Answer 4

Your bootloader type is probably UEFI boot. Change to Legacy and you should be fine.
