[SOLVED] Reinstalling Linux mint over a old failed version

Postby Jo71236 » Fri May 19, 2017 10:25 am

So about a year and a half ago the version of linux mint I had dual booting on my computer failed. Grub wouldn't load and it would boot straight to windows. Now suddenly remembering my hard drives still partitioned I thought i'd install the newest linux mint after wiping the old version. Problem is, I have no idea what partitions to delete. Here's my screen shot of gparted anyone mind telling me what partitions to delete? That'd be great thanks!

you don't delete it or even uninstall it,
but rather tell the new installer what to do:
- - use the something else option:
then use the change icon to select in turn:
- sda7 as the / root partition
- sda9 as the /home partition
- sda8 as the /swap partition

and click on apply & next to format sda7 & sda9 & then on next, to continue with the install.

Note: this assumes that you don't have anything to keep, on those partitions
& in particular on sda9 - -

Swapoff /dev/sda8 and delete swap-partition. After that delete /dev/sda7 and make a new partition to the empty space.

For / partition give 30 GB and make a swap-partition too (about 5 GB). When installing select 365 GB partition for /home

It's either sda7 or sda9; I'd guess sda7="/" (OS install) and sda9="/home".

You can tell by looking at the partitions with a file-browser: the OS partition will have "bin etc lib ..." directories.

You don't have to delete anything, just mark the partition for "format". 20G is about right for "/".

Your data and OS are backed up....right?

that's a point - - sda8 - the /swap partition - that size is only needed if you wish to hibernate,
& that your PCs ram is 16Gb in size - - otherwise it's 3x too big.

Alright thanks for that. as grub failed do I need to reinstall that somewhere? Or will the installer do that for me?

I have 8 gig's of ram I think I remember reading somewhere double your ram is what you should have your swap as. Either way hibernation is a nice function to have so should I just make the partition smaller?

yep - the installer will place the Grub Loader onto SDa

you can just take the easy option & format & re-use,
or you could follow administrollaattori suggestion to re-size things a bit.
- either way, will work A.ok

Alright thanks for the resizing recommendations!
