Hi All After the posts last week about android I thought I would try android-x86 on my Samsung Slate currently running Debian Buster. At first I tried the rpm version using alien. The scripts configure android with qemu and also adds a grub entry for dual booting. The qemu version works well. When I tried to boot neither android nor Debian would boot. Android would just return to the grub screen and Debian would stuck at ' Loading Linux 4.19.0-4-amd64' . So more fool me for trying the alien rpm root. So boot with rescue usb, chroot, and alien -e android-x86 to remove android. Update-grub and reboot. All OK boots into Debian. So make Android-x86 boot usb and reboot into installation mode. Install Android into /dev/sda1 without formatting as per http://www.android-x86.org/documents/installhowto. Do not install grub. Installation finishes. Option to run android with out rebooting, works fine. Reboot and can't get passed grub. Same symptoms as before. Booting with rescue usb, chroot, and update-grub appears to work but after reboot won't get passed grub. Then at grub screen click on c and get grub shell. set root(hd0,1) and get the grub prompt again, using ls I can see all of the required files with tab to autocomplete so, linux /boot/vmlinuz-4.19.0-4-amd64 root=/dev/sda1 sticks. Doesn't return to grub prompt. No timeout. Get supergrub usb. Boot, sees the partition and can boot Debian. What am I missing here? I getting close to nuking everything and reinstalling. Any ideas? Cheers Nic
