i am trying to install Ubuntu 18.04.06 on my Laptop (Lenovo ideapad 450u) on a 200gb ssd. The installation works without any Problems, but once the Installation is finished, and i try to boot the drive, it doesn‘t appear in the boot menue (CSM Bios, UEFI is not supported). To test if it was just linux causing the Problem, i tried to install windows 7, but turns out, i cannot install it, with the error message „could not create a new system pattition or find an existing one“ another error message i get (in german)

I think the Problem lies on the drive itself, and so i thought, that i could create usb bootloader, that boots the os on the drive. I looked at some Solutions online, but couldn‘t find one that fits my problem. Can you guys help me out?

to install Windows, reboot with your USB, press Shift+F10 or select repair your computer, select command prompt, and apply:

diskpart
lis dis
sel dis 1 # replace no. 1 with your hard disk number 
clean
cre par pri
format quick fs=ntfs label=Windows 
assign letter=C
exit

reboot to install Windows as normal state.

After installing Windows, use Rufus or Ventoy to make an Ubuntu live USB and try to install Ubuntu alongside Windows.

Update:

Windows cannot be installed on the disk. Your computer's hardware may not support booting from this disk. Make sure the disk's controller is enabled in your computer's BIOS menu.

the error message says that you have to enable the disk's controller in your computer's BIOS menu
