I picked up an Ideapad 100s and have been trying to install Ubuntu on it. So far I have been unsuccessful to boot the Ubuntu installer. That machine comes with windows 10, uses UEFI and its setup only allows to disable Secure Boot (does not have BIOS compatibility mode). I was able to create a windows restore USB flash drive and used it to verify that the system has capability to boot from EFI USB drives (Fn+F12 for boot options).
ubuntu-15.04-desktop-amd64.iso and tried two ways to write to USB media:
dd if=ubuntu-15.04-desktop-amd64.iso of=/mnt/sdbthen rebooted the ideapad onto boot options, but the EFI boot menu shows Windows Boot Manager as the only choice.
I mounted the iso onto
fdisk) with type vfat and made it bootable. Created fs onto
mkfs.vfatand mounted it onto
/mnt/sdb1. Then used
cp -a /mnt/iso/* /mnt/sdb1to copy all the content. Booted the ideapad yet the boot menu only showed Windows Boot Manager as a option.
Was looking at related posts (e. g. Problem Installing Ubuntu on Lenovo Ideapad U330p) and seems that other machines easily recognize the Ubuntu loaded USB flash drive. This is a nice lightweight laptop I would like to keep, but only if I can install Linux on it. This first hurdle of actually booting Ubuntu installer seems already large (probably would see lots of device issues under Linux–but I'd be glad to get that far).
If anyone has any ideas for me to try, I would be grateful.
Edit #1: I tried booting with http://cdimage.debian.org/cdimage/weekly-builds/multi-arch/iso-cd/debian-testing-amd64-i386-netinst.iso (used
dd to write to flashdrive
/dev/sdb) and the ideapad UEFI boot menu now gives me the choice for 'EFI USB Device'. I select it and next screen is GRUB prompt. Something is not right, but it's some progress from before. What this tells me is that the amd64 Ubuntu iso image has
efi/boot/bootx64.efi but this ideapad's Firmware needs 32bit
.efi file. The Debian img above has both the 64bit and
efi/boot/bootia32.efi. Why does it get stuck at
grub> is my next mystery to solve. This is starting to sound similar to Ubuntu on Asus X205TA and http://ubuntuforums.org/showthread.php?t=2254322.
Edit #2: So I copied
bootia32.efi from the Debian release onto
efi/boot/ of Ubuntu 15.04 and tried booting with that, but ii gets stuck at the
grub> menu as well, and I could not have it boot
vmlinuz. I then noticed that this machine is running windows 10 32bit version, so I went to look for the 32bit Ubuntu version. No luck: neither 15.10, nor 15.04, nor 14.04 have
EFI/ in it.
So I went for the Debian i386 version. I got the grub menu, hit Install, and it progressed to the installation screen. The installer asked for language selection, and there I found that it would not accept key presses from the ideapad's own keyboard (later when I chose the graphical install, it would not take mouse input either). I plugged in a USB keyboard which was recognized correctly enabling me to make the menu selections. I plugged in a USB WiFi dongle and it was recognized, but it would not load the
rtxxx firmware so that halted my installation.
I switched to a terminal with Alt+F1 and
lspci was only showing 5 entries:
00:00.0 Host bridge, 00:02.0 VGA compatible controller 00:14.0 USB controller 00:1a.0 Encryption controller 00:1f.0 ISA bridge
It does not seem like Linux can detect all the hardware. Even
/proc/cpuinfo only reports only one processor. I'm afraid that the 4.2 kernel in Debian's
debian-testing-i386-netinst.iso (updated at 2015-10-12 12:53) is not ready yet to work with this laptop.
I'm almost ready to stop trying (and return it).
