While installing Ubu 15, I accidently pressed f4 instead of f2 at boot and went into Windows recovery. Normally not a problem. Now, if I set boot mode to UEFI, only Win is available. It is not possible to choose any other option, viz a viz boot from a usb stick. I can only boot usb when I set UEFI + CSM mode in the bios.
Following instructions from the link https://help.ubuntu.com/community/Boot-Repair I used apt-get on a Live usb stick Ubuntu15 iso to get Boot Repair and then ran it.
I cannot boot the usb stick Live iso in UEFI mode. If I set UEFI mode, only Win boots. So I set boot mode UEFI + CSM The boot stick boots, I run Ubuntu, Boot Repair runs for a while then says:
"The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd (http://www.sourceforge.net/p/boot-repair-cd)), after making sure your BIOS is set up to boot USB in EFI mode."
Question: with the boot mode set to UEFI + CSM is it possible to force the system to boot UEFI? Only then will I be able to run Boot Repair and maybe then it will do its stuff.
To complicate matters:
I made a Boot Repair usb stick with UNetbootin, from the bootrepair64bit iso. It too cannot boot if boot mode is set to UEFI
I have fast bios mode = disabled, secure boot = disabled
It boots when I set the mode to UEFI + CSM. Then I get the error
(initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: invalid argument
Can not mount /dev/loop0 (cdrom/casper/filesystem.squashfs) on //filesystem.squashfs
Tried all the options in the initial boot repair menu, same result, including failsafe.
Any tips out there? Wipe out the disc and start from fresh? But that would not affect the bios, would it?
Here is boot repair info. You can see /dev/sda3, 7 and 10 seem to have problems, and they are win related partitions.
