No boot after boot-repair (uefi)

[franky2]

After boot-repair: I reboot and nothing happens. Only grub2 menu appears with choices of ubuntu and advanced ubuntu options but neither load.
they get stuck at (initramfs) switched to clocksource tsc..

I am new to the forum so please excuse my errors/ignorance or lack of info )
I was running boot-repair tool cause of black screen in booting and followed instructions:


Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda (500GB) disk!


I think I did not set the boot on sda in bios.
Any ideas what to do? I wanted to install Xubuntu (that I liked better) and I already have it on a usb stick, but it does not load it..

Any help would be great

Thanks
Franky

Any help would be appreciated.

This is generally a graphics issue, which is usually remedied with using 'nomodeset' option.

parted -l:

Model: ATA TOSHIBA MQ01ABF0 (scsi)
Disk /dev/sda: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Disk Flags:

Number  Start   End    Size    File system     Name  Flags
1      1049kB  538MB  537MB   fat32
2      538MB   498GB  498GB   ext4                  bios_grub
3      498GB   500GB  2012MB  linux-swap(v1)        bios_grub

Using Gparted remove the 'bios_grub' flags from both, 2 & 3 parititon or /dev/sda2 and /dev/sda3.
Secondly, add a 'boot' flag to /dev/sda1 or your first partition.

See if you are able to boot..

If you can't then Re-run Boot-Repair tool, use Advanced options and install Grub to ESP [EFI System Parttion], which is /dev/sda1 or the FAT32 partition to which you added a 'boot' flag.

Thank you very much for your help Fantab, but as I cannot boot into any mode so I don´t know how to actually run the boot-repair tool like this

Please do not double post about the same problem.

Personally, I would like to see a screenshot of Gparted showing the partitions. That Boot Repair report does not show one Ext4 partition with Ubuntu on it. And that is unusual. Are you running Boot Repair from a Live session or from Xubuntu installed on the hard disk.

=================== os-prober:
/dev/sda2:The OS now in use - Ubuntu 14.10 CurrentSession:linux

=================== No kernel in /media/laura/C8A7-9A41/boot:

And yet there is this

update-grub

thanks for the help grahammechanical, I was running boot repair from Lubuntu installed on the disk. But now I cannot run anything as it gets stuck on boot, so I cannot take screenshot of Gparted showing the partitions. Or I don´t know how to access this info.

Sorry for the double post oldfriend, I thought I posted in the wrong place, that´s why I did it again in "New in Ubuntu". Won´t do it again

I tried the For info on UEFI boot install & repair:
http://ubuntuforums.org/showthread.php?t=2147295

but apparently instead of fixing what Fantab said must have been an graphics issue, I made matters worse...

You can run Ubuntu or Lubuntu live installer and add Boot-Repair or run other commands to update system.

You may need to change UEFI/BIOS settings. Try both UEFI and BIOS, but you really are UEFI and only should boot in UEFI mode.

And black screen is almost always video related. What video card/chip do you have?

?

That was my problem...I connect the usb and boot but I don´t know how to access the live stick as I get stuck on the grub2 menu with 2 options Ubuntu or Ubuntu advanced settings (that neither boot). Is there a command I can run from there to boot from usb stick?

Do you know any commands to access it without booting into Lubuntu ?

Computer was new and I din´t get the chance o check...

thanks sooo much for the help !!
