The only solution I can see for that :
A ::
1 - take out the C drive
2 - plug it on a working computer
3 - do the installation
or..
B ::
The Bios Should recognize the USB port, unless it's broken. So first, check this.
> "Esc" key at the boot to access the Bios
If the Bios recognize your flashdrive usb key :
> download the USB bootable image of the OS you want to install
> and install by selecting the USB flashdrive as Boot option in the Bios
If not :
Check the USB plug (the one on the computer..)
If it works.. I guess..
Back on A ::
