Hi,
I'm trying to set up a windows 10 dual boot on my computer (for gaming), which runs ubuntu only. In making the bootable usb, the ISO file is too large for fat32. How do I compress it without windows only applications?

I agree with Mohittomar13. While it's perfectly possible to compress lots of files further still (even if they're already in a compressed state), it's neither desirable nor advisable to do this with an ISO file.

You'll corrupt/degrade the ISO9660 file-system format used to create them.....and then it won't work at all. You need a larger flash drive, I'm afraid. No two ways about it.

In addition to this, you will never be able to install anything larger than a 4GB file size to FAT32 system. It's an inherent limitation of FAT32. If you want to keep with FAT, AND want file-sizes larger than 4GB, you'll need to move to something like ExFAT.....and I doubt Windows will install to this. I don't think Ubuntu will like it either.

Windows expects NTFS. Mainstream Linux distros expect Ext4.

Mike. ;)

A bit late to the party, but since this machine has only Linux, you will need to pay for a Windows 10 license or you will get the dreaded Activate Windows message then (supposedly) Windows limits you dearly.
