if I do a clean install of Windows on a dual boot system, will Windows format the whole disk and remove the Linux install, or will it only clean the partitions that belong to Windows?

in this situation, you would use a live booted linux distro first, and shrink the existing linux ext4 partition by at least 50 to 80 GB using the gparted application's resize command.

#

leave the resulting space as-is (unallocated)

#

then fire up the bootable Windows installer medium, and proceed to install onto that space.

deep python
#

I

#

I already have Windows installed, I'm not looking to set up a dual boot environment

#

I'm trying to do a clean install of the already existing Windows install, without breaking the exisitng dual boot Linux

vast scarab
#

so u just want new windows on it, no linux?

deep python
#

no, I want to keep the Linux

vast scarab
#

same idea as was said, just delete the windows ntfs partition

deep python
#

I have both Windows and Linux, and I want to reinstall Windows

vast scarab
#

do not delete the EFI system partition though no matter what

#

unless it's old pc/ legacy boot

deep python
#

yeah, I figured I have to stay away from the EFI, but does that mean all the other partitions are fair game? Except the Ext4 linux one, obivously

vast scarab
#

yes u can remove ms reserved , ms-recovery

deep python
#

alright, nice

#

man, these windows partitions are all over the place, what a bloated OS lol

vast scarab
#

are u logged on rn?

deep python
#

how safe is it to move the EFI partition using gparted?

deep python
vast scarab
#

open disks app

#

click the drive

#

read the middle

#

is it guid partition table?

deep python
#

yeah

vast scarab
#

good

#

is it ssd?

deep python
#

yup, M2 nvme

vast scarab
#

how much data used on the linux part?

deep python
#

about half, total capacity is 376 gb, free space is 192 gb

vast scarab
#

yeah u could move the efi partition to the very left, followed by the linux ext4 one, and the rest just is unallocated space

deep python
#

perfect, that's exactly what I want

vast scarab
#

u'll need to do it in live mode

deep python
#

that's when it's booted from usb, right?

vast scarab
#

make a usb of linux ya

deep python
#

a linux usb, not a gparted one?

vast scarab
#

most come with gparted

deep python
#

aah, right!

#

I already have the Linux Mint Cinnamon 22 ISO, I guess I can just use that

vast scarab
#

yep

deep python
#

sweet, thanks!

vast scarab
#

check now in linux terminal

#

efibootmgr

k so after cleaning and prepping windows iso, make sure to boot that stick as uefi device to install

deep python
#

how do I boot as uefi device? I've always just gone to my BIOS and picked a boot device whenever I want to boot from a usb

vast scarab
#

should say uefi in front of it, or a "u" if icons
