Is this a booting problem in 18.04.2 or is it my imagination. I think not. I don’t remember, ever, on Ubuntu. It is occurring far too much. It now works, but I expect this to occur again. Is this a problem with Google or other search engines or what I say? Should I go with Ubuntu 19? with the same problems?
I dun goofed. I thought my Windows was booting using UEFI, and I installed Ubuntu using UEFI. But now I think my Windows was booting using MBR, and GRUB can’t detect it.
I’m confident the disk is MBR:
> sudo gdisk -l /dev/sdb GPT fdisk (gdisk) version 1.0.3 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: not present
and that I’m booting via UEFI:
> ls /sys/firmware/efi/ config_table fw_platform_size runtime systab efivars fw_vendor runtime-map vars
How can I fix my GRUB so that it boots using MBR instead of UEFI?
Neither gave me a GRUB menu with Windows listed.
My client machine(which is a desktop) has PXE capabilities for sure with wake on LAN. Is there anyone who tried this Pliggly or similar sort of things.

I have downloaded a Plymouth theme from Gnome-loo.org. And since it was a deb package, I installed it through Ubuntu Software. Then, I typed “sudo update-alternatives –config default.plymouth” and selected the newly added theme. But it didn’t work out at all, and Plymouth theme didn’t change. If you know how to do it properly, please let me know. Thanks.

I made an USB bootable using transmac in windows but whenever i tried to select the bootable USB using Option + Power button, it loads half the bar and the screen shows prohibitory sign like the “phi” sign. Any suggestions, how to clear it out?
I have problems getting kubuntu installed and dual boot together with windows 10. I have two disks one for windows and one kubuntu. I would like to have grub installed on the kubuntu disk and have it dual the windows.
Boot-repair gives this output:
I have tried the os-prober, grub update and boot-repair but none of them gives a installation that produces a grub menu item to boot windows. If I change my bios to boot the windows disk it works fine. Booting the ubuntu goes fine from the disk with grub/kubuntu.
It looks like I need the boot-repair to find my windows installation before I can get this to work. But how?
I have a server on OVH with Cpanel which has 2x2TB partition and its lsblk command output looks like this. http://prntscr.com/nz4xd2 Few days back I ran some upgrades and after reboot my server didn’t boot properly and it halts during boot process and gave prompt like this:
I did some RnD and I was able to boot the server by running following commands on grub prompt:
set prefix=(hd0,gpt2)/boot/grub2 set root=(hd0,gpt2) linux (hd0,gpt2)/boot/vmlinuz-4...…… root=/dev/md2 ro boot
Then I searched for its permanent solution which takes me to some URLs like this https://www.linux.com/LEARN/HOW-RESCUE-NON-BOOTING-GRUB-2-LINUX which suggest to reinstall grub using commands:
# update-grub # grub2-install /dev/sda
I am on Centos which doesn’t has command:update-grub but I was able to run other command:
[root@server2 ~]# grub2-install /dev/sdb Installing for i386-pc platform. Installation finished. No error reported.
after this Upon reboot I again got the same grub prompt.I am not sure what is wrong here. Can anyone please suggest something.
I have Windows 10 installed already, and am trying to dual-boot with Ubuntu desktop(19.04). However, after finishing the dual-boot installation (allocating memory), Ubuntu asked for a restart, and upon restarting, my screen was filled with “squashfs” errors. After a long period of waiting, I decided to force shutdown. After turning my computer on from the shutdown, there was no Ubuntu dual-boot menu, and Windows was immediately booted. I decided to go to Window’s disk management application (diskmgmt.msc) to delete the memory I allocated to my failed Ubuntu installation, and reattempt to install Ubuntu. However, when I am on the advanced startup page to attempt to boot from my USB to reinstall Windows, there is still an option to boot from Ubuntu, even though I already deleted the partition containing it. When I attempt to boot from it, (can also be accessed from default boot menu upon computer startup), I am greeted with this GNU Grub shell. Can anyone direct me on what I should do?
