Here's what I did:
1. Download the Debian 9.5 amd64 iso
2. Install the iso on a USB stick using Rufus portable
3. Edited grub.cfg in /boot/grub/grub.cfg, and added the following lines (in bold):
Booted from the USB - still no avail. Black screen after selecting the "Install" option.menuentry --hotkey=i 'Install' {
set background_color=black
linux /install.amd/vmlinuz vga=788 --- quiet
initrd /install.amd/initrd.gz
modprobe.blacklist=ideapad_laptop
ivrs_ioapic[32]=00:14.0
ivrs_ioapic[33]=00:00.1
}
I would be grateful for any advice.
Thank you
