Phil;
Do you have a short write up by chance on how to run the miners on Ubuntu?
there was step by step on how to install linux on a pc it is on a thread maybe mikestang told me let me look back for the link
it very much depends on whether you want it to run in dual boot mode (win AND Ubuntu) or just replace windows with ubuntu (much easier).
Second, it depends won whether you have win 7 or win 8-10 computer. The latter ones have UEFI BIOS (instead of Legacy) and it really depends on the computer.
If yours is HP win8, I can provide some writeup.
This description is OK, but every BIOS is different:
http://askubuntu.com/questions/221835/installing-ubuntu-on-a-pre-installed-windows-with-uefiIn short:
1. first, you need to create a partition for Ubuntu by shrinking your Windows partition
1. then, you'll need to right click on startup, go to power options and unclick "fast startup" there.
this is described here:
http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html2. then restart while holding the shift key...you will restart into "bluish menu"
then "Troubleshoot', then "UEFI firmware settings"
you will be asked to reboot or restart and you will be booted into BIOS where you can change things.
IMPORTANT:If Windows 8 was installed with UEFI enabled, it is highly recommended to stay in UEFI, although if you still want to disable it for specific reasons you can, GRUB will create the bootable part for Windows 8. But if you do disable UEFI and want to access Windows 8 afterwards (before installing Ubuntu), it will not work since the boot part for Windows 8 needs UEFI (Again the Dual Boot problem).
For my HP win 8.1 computer, all I needed to do was to change boot order from first being windows boot manager to first being DVD, second flash drive, then third Windows boot manager. The BIOS menu commands are archaic, but if you messed up, you can always save with default settings of save without changes and try again. The ONLY other thing that I had to do was to again disable fast boot, now in BIOS. I left secure boot and other settings in SECURITY area untouched because when I tried to do it, it wouldn't start from the DVD.
Then, save the BIOS settings and restart. Next time, insert ubuntu DVD or usb stick, again press Shift key on restart, but now in bluish menu click on UEFI icon, then chose your DVD or USB (it should also have UEFI in its title), then restart. Hopefully, you will be booted into ubuntu installer and proceed from there.
Jake36 provided an almost perfect writeup how to install cgminer-gekko on Linux (in support thread) with only caveat being that at the end you should
instead of cd cgminer-gekko, then run as sudo.
