Hi
Very new to ubuntu, but some experience of Macs and linux commands and using terminals etc...
Super keen to get ubuntu set up as dual boot with W10, but having a few issues..
I have a checksum verified ubuntu 18.04 LTS ISO and created a bootable USB using rufus. My machine is probably >5 years old now and uses MBR / BIOS (although the Gigabyte boot up splashscreen does indicate that is is Dual BIOS and UEFI...)
I created freespace in windows using diskmgr and then booted from ubuntu live USB to start the install...
I have run boot-info and here is the output: paste.ubuntu.com/p/dmz69QwkkQ/
(http://paste.ubuntu.com/p/dmz69QwkkQ/)
Issues and what I have done to try and rectify:
Windows was not detected by the installer, no "Install alongside" option, so I went down the "Something else" route and manually created partitions...
I got the warning about "NO EFI System Partition was Found" but continued with the installation...
After installation I rebooted, but straight to W10, no dual boot screen
I have followed through most of the suggestions here: https://medium.com/isdanni/ubuntu-18-04-lts-dual-boot-with-win10-bios-legacy-mbr-c2d12308374c - particularly editing the boot file the boot-repair stuff...
I used EasyBCD to add a new entry to the boot menu. Now when I boot, I get the Windows dual boot screen fine and W10 boots fine. However ubuntu does not boot - just hangs with a large flashing underscore cursor at top LH corner of the monitor
I ran boot-repair as per these instructions (https://help.ubuntu.com/community/Boot-Repair). When I ran the "Recommended Repair" option, I was presented with 3 commands to run in the terminal to edit the grub-pc, however, the first command fails
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
dpkg: error processing package grub-efi-amd64-signed (--configure):
installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1
dpkg: dependency problems prevent configuration of shim-signed:
shim-signed depends on grub-efi-amd64-signed; however:
Package grub-efi-amd64-signed is not configured yet.
dpkg: error processing package shim-signed (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:
grub-efi-amd64-signed
shim-signed
These are the 3 commands (output of the 1st command above)
sudo chroot "/mnt/boot-sav/sda7" dpkg --configure -a
sudo chroot "/mnt/boot-sav/sda7" apt-get install -fy
sudo chroot "/mnt/boot-sav/sda7" apt-get purge -y grub*-common grub-common:i386 shim-signed
I didn't do any of the grub rescue stuff suggested on the medium.com (https://medium.com/isdanni/ubuntu-18-04-lts-dual-boot-with-win10-bios-legacy-mbr-c2d12308374c) link... I thought I would check in here before getting any deeper...
May be I should have created a small partition for with an efi mount point... If so, how do I rectify that now? I already now have 4 primary partitions on my SSD drive, so GParted will not let me create a logical one without removing the physical one (which contains the ubuntu install... :-/)
May be I should have disabled secure boot, but my BIOS settings don't seem to have an option to disable it and I'm not sure how to know if it is running or not. My assumption is that it is running as it probably would have done by default when it was new and I haven't disabled it ever AFAIK.
Should I uninstall ubuntu (if so how), create an efi partition and then start again?
OR should I repair the grub stuff? If so how
OR should I do something else??
Thanks very much in anticipation...
