Wanna try SteamOS, but have a UEFI Motherboard, heres a workaround
Heya people, its been a while since I made a blog post so I have one for you all today, given the release of SteamOS Beta was the other day I decided to try it out, they said it will only support UEFI motherboards, my board has EFI booting for CD/DVD only but making a bootable DVD isn’t available using windows from my knowledge so my only option is the USB methods, I then found a handy post over here about making a bootable usb for Non-UEFI motherboards, I’ve yet to try it but I will be shortly, I will update + post back results and maybe some screenshots, enjoy gaming with a dedicated gaming OS!
Method 1: Grub and SysLinux
This method is provided with great thanks to /u/FrostyCoolSlug of Reddit. Please use extreme caution when trying any of these steps, and I am not responsible for any damage to an existing computer installation.
- This configuration will automatically wipe your hard drive and install SteamOS as soon as it’s finished booting. Don’t use on a real computer unless you’re REALLY sure.
- I take no responsibility if you break your machine following these instructions!
- I’m not going to “support” this installation method, it’s very much a “Works for me” situation, YMMV.
These instructions assume your USB pen drive is on D: – Adjust where relevant
Step 1: Download syslinux from Here
Step 2: Download the following two Grub packages* and place them in D:\grub (you may need to create it)
Note: if for change, those files are removed, I have uploaded these to my public bitorrent syncdirectory here:
- Install BitTorrent Sync
- Create a folder in your home directory
- Use the key “BWSL4QC5J7E5HSLNHNR4BSIBA47E6DOZB”, to add the sync folder
Step 2: Extract the SteamOSInstaller.zip file to the root of your USB drive
Step 3: In the root of your USB drive, create a new folder called syslinux
Step 4: From the downloaded syslinux zip file, extract bios/win32 and bios/mbr into D:\syslinux\
Step 4: Open a Command Prompt as Administrator and run MAKE SURE YOU CORRECT THE DRIVE LETTER!:
d:\syslinux\win32\syslinux.exe --install --mbr --active d:
Step 5: Create the file D:\syslinux.cfg and put in the following:
DEFAULT linux TIMEOUT 50 LABEL linux kernel install.amd/vmlinuz append initrd=install.amd/gtk/initrd.gz preseed/file=/cdrom/default.preseed DEBCONF_DEBUG=developer desktop=steamos auto=true priority=critical video=vesa:ywrap,mtrr vga=788 -- quiet
Step 6: Insert the USB drive into the target machine and boot, the installer should run.
Step 7: The installer will FAIL when attempting to install grub, as grub-pc is missing, hold Ctrl+Alt and Hit F2 to drop into a shell, hit Enter to activate it.
Step 8: Type the following and when prompted, do not select any drives, just hit OK and then ‘Yes’:
chroot /target /bin/bash
apt-get install grub-common grub2-common
dpkg -i /media/cdrom/grub/grub-pc-bin_1.99-27+deb7u1+steamos3+bsos1_amd64.deb
dpkg -i /media/cdrom/grub/grub-pc_1.99-27+deb7u1+steamos3+bsos1_amd64.deb
Step 9: Once that’s complete, Hold Ctrl+Alt then hit F5 to return to the UI
Step 10: Hit ‘Continue’ to try grub again, this time it should run properly, say ‘Yes’ to installing to the MBR and the installation will complete.
Step 11: Once installation is complete, follow the rest of the guide Here
* Note that the grub packages are hosted by me (edit: /u/FrostyCoolSlug), they are simply the standard debian builds with the DEBIAN/control file edited to repair dependency problems, and re-versioned to reflect their SteamOS usefulness.
To boot from USB, download this , extract plpbt.iso and boot from that, it’ll allow a USB boot. Note that ‘Enable USB 2.0 (EHCI) Controller’ must be DISABLED.
“I am stuck on now is “Run steam, accept the EULA, and let it bootstrap. Logoff the steam account”.”
run steam from a terminal for it to work, once I was on the login screen, I quit steam then logged out the steam user, then jumpped into desktop and executed the script.
Ran the script, it rebooted into capturing recovery partition mode then something failed and threw me into (initramfs) prompt. I rebooted into “normal” mode again and after the loading finishes I get stuck with a black screen.”
This was caused by having two screens attached. Disconnecting one of them helped.
“I’ve noticed it sometimes seemingly dismounting my USB drive, not entirely sure what causes it, try it again and see if it’s any better… There may be a driver issue otherwise, I’ve only done my testing in VirtualBox.”
If you Ctrl+alt+F4, the logs might explain why it’s not working.
