Linux Mint Forums

No, I don't use fedora which is why I suggested you ask on a fedora forum.

Legacy = the old way of installing/booting systems (dates back to the 1980's), UEFI = the new way (since about 2010). Doesn't matter which distro, linux installs in the same mode your install stick boots in. So you need to boot your fedora install stick in UEFI mode. To do that, disable the CSM flag...

Based on your last posts I can explain it. OS-prober (used by grub) will only find other OS installed in the same mode. Win is installed in UEFI mode: path \EFI\MICROSOFT\BOOT\BOOTMGFW.EFI Both fedora and mint are installed in legacy mode, but... With LM21 when you install in legacy mode, it also cr...

What MiZoG has suggested will work, but requires you to use a terminal text editor (sudoedit). You might find it more comfortable to use a GUI text editor. When you have mounted your / partition ( sudo mount /dev/sda4 /media/myborkedsystem ), open your file manager (nemo if cinnamon), navigate to /m...

This is the offending entry that disks created in fstab: /dev/disk/by-uuid/7b479b37-0f01-4a7d-8dec-4c1ba0b7a6c8 /mnt/7b479b37-0f01-4a7d-8dec-4c1ba0b7a6c8 auto nosuid,nodev,nofail,x-gvfs-show 0 0 Taking it apart: /dev/disk/by-uuid/7b479b37-0f01-4a7d-8dec-4c1ba0b7a6c8 This defines the partition to be ...

Excuse me if my post was ambiguously worded. The drive IS mounted at /mnt. Would it be advisable to create a new mount point mnt/USER and remount the drive at that mount point? Yes, if you add further drives/partitions and want to mount them in /mnt . In linux you can mount partitions anywhere you ...

Boot your install stick and undo the changes you made to fstab.

It sounds like all three OS are booting legacy. You can confirm in mint/fedora with efibootmgr . If it says EFI variables are not supported it is legacy, anything else is UEFI. In win I think msinfo32 tells you. I'm speculating, but you are booting fedora off a drive with a gpt partition table and a...

Obvious question - when you installed win10 it will have put itself at the top of your BIOS boot list. Have you been in BIOS and put "ubuntu" back at the top? Do you still have an ubuntu entry in your BIOS boot list? If it was in the EFI partition on your win drive it probably got wiped by...

Your screenshots show both mounting in /media..... so where are they not recognised??

I also use backintime. When you install it you get two menu entries backintime and backintime(root). You could setup a profile for backintime(root) that only snapshots your MySql files irrespective of where they are in the file system. I've never used the root option so I suspect it will prompt you ...

I see the background darkened when I lock the system, why is that a problem?

What did you do to "fix" grub and what was wrong with the existing menu? With legacy boot you can only have one bootloader per drive. It lives in the first sector on the drive.

My bad, I should have checked my fstab

You are trying to use the latest ntfs3 driver and it is not in your kernel (not sure what kernel LMDE ships with). Follow altair4's advice, I expect there will be a line in fstab with ntfs3 as the filesystem, replace with ntfs for the old driver.

Notes to altair4's comments. I always add user to the fstab options, without it only root can mount/unmount. If you mount in /media it will show in the devices pane in nemo as DATA (remember linux is case sensitive). If you don't want it to show in the devices pane, mount it in /mnt . You have to ed...

A "better" way to mount your synology is a cifs mount in fstab, this is how I do it:

I have enabled SMB1.0 but this is not needed for cifs.

Installing a VM in VB is a two step process, the first time is setting up the virtual drive the second time you run it, it asks where is the CD or iso to boot from. If you are not being asked where the iso is, on the VB devices menu > optical drives > choose a disk file and navigate to the win10 iso...

How and what did you use to clone the drive?

My EFI partition is 100MiB and 7.6MiB used - this is mint only. Even with dual boot win, used would be around 40MiB. What are you doing that requires more?
