Trying to install LM but it wants a root partition SOLVED!

Post by freshtamatic »

I'm trying to install LMC on an empty partition (the laptop already has a different distro). I choose 'something else' during installation and select the unallocated partition. Once I choose it, it asks for a root partition. I don't know what it means, I tried selecting other partitions but it wont accept it. Can someone help?

Are you assigning the partition with a / mount point? You need that at a minimum.

I did try it, but it still wanted a partition.

It still asks for a root file, or an EFI something.
lsblk:

restart the entire install media (not just the installer) in CSM Mode rather than EFI Mode. The other distribution was installed in CSM Mode so there is no EFI partition.

choose 'something else' during installation and select the unallocated partition.
When you choose that option, it is up to you to decide how the device is to be partitioned. Selecting that option tells the installer to mind its own business, which means you need to know exactly how to set it up, then you actually set it up, then you tell the installer how you've set it up. In short, you must manually create the partitions and assign them to mount points, / (root) being one of them.
Coming to a thread near you: Lots of bragging about my AMD 5950X. Currently delayed due to high demand.

That would indeed be different than a root partition. Regardless, I would suggest going with antikythera's recommendation to resolve this.

If you really want to embrace the UEFI world (for reasons unknown), you just need a small partition for the EFI stuff. More info ... https://en.wikipedia.org/wiki/EFI_system_partition

Otherwise, boot the installation media without EFI, most commonly achieved via the computer's boot menu.

Don't want EFI, any tips where this might be found in the BIOS?

For the install, you should just need to boot it via the computer's boot menu. Doing so is different for each computer, but it's usually one of the function keys that brings it up when you first power on. Perhaps it even says what key it is during power up.

Edit: It's often called Legacy Mode on boot menus that I've seen.

I'm on an ASUS, I tried F2 and F12, only the former brings me to the BIOS. F12 does nothing. I'm running out of ideas :(
I've enabled legacy mode.
Is there a way to burn the USB key so that it isn't UEFI?

As such, does the installer now still ask for a EFI partition?

It's not how the USB drive is burned, but how it's booted.

-- A consistent way I've done from within Windows to create a legacy mode compatible OOTB linux mint installation thumb drive ( or ssd in my case) is using AOMEI partition assistant ( and yes the free version works) to format that installation drive as fat32. Depending on the capacity of the drive, Windows cmd as well as its own built in partition creation/editing gui tool want to be stubborn and refuse to do it beyond a certain size. AOMEI partition assistant just works without a hassle.

So you can grab a spare 64GB or bigger ssd or thumb drive, use that software to partition it as fat32, then just download the LM iso of your choice, copy and paste it directly into the drive. Then right click on it and " extract here". Now it's bootable. As long as you've ensured that that legacy mode is enabled in your Asus bios/setup/uefi settings, there is no reason why it shouldn't boot as well as allow the option of booting LM into compatibility mode if needs be for more guaranteed success in installation

Just remember if it's cinnamon, select " continue testing" so you can software gui power down that PC and then you can remove that installation drive at your own pace instead of playing the guessing game of hoping you don't remove it either too early ( which sometimes just goofs the grub booting) or too late and you're right back at booting from the LM installation drive. Mint Xfce since either 19 or 20 doesn't have such an issue to worry about at the end of the installation wizard.

Hope this helps. CHeers--

Did you try tapping the delete key during start-up? That may bring up your BIOS and changing to and from CSM may be under the security tab. Maybe...just look around.

I finally figured out and now I can choose start up from the boot loader and it shows both UEFI and plain USB, so I'm ok!
Thank you all for the help.
