How to Dual Boot Windows 7 with Linux Mint 20

My PC is running Windows 10 32 Bit on partition 1 and Linux Mint 64 BIt on partition 2.
How to REPLACE Windows 10 32 Bit with Windows 7 64 Bit??

Or Can I replace Windows 10 32 Bit with Windows 64 bit without affecting Linux Mint??

Thank you in advance!!

Hello Niraj,

Windows 7 has reached end of life. There is no point in using an operating system that won’t get security and maintenance updates.

Welcome to “It’s Foss” @BLENDER_NIRAJ. As @abhishek said, I too would stay away from Win 7.
And unless you have more then 4 GB of ram install, a Win 64 bit system will be of little benefit. In fact, I found this on the web;
“Does 32 bit run faster than 64 bit?
Short answer, yes. In general any 32 bit program runs slightly faster than a 64 bit program on a 64 bit platform, given the same CPU. This is measurable and undeniable. …”

So you might be better off staying with your Win 10 32 bit system. Good Luck.
