Windows 10: Cannot install win 7 as dual boot as it can't be install to the select

I currently have a windows 10 system (latest version 1909) that is install to an SSD as UEFI. I also have a 2nd drive which is a standard HDD that has 3 partitions. I want to install 7 to one of those partitions but when I attempted the install it will not install saying it cannot do it to that drive.

When I check in disk manager the SSD shows as GPT but the 2nd drive shows as MBR and I assume that is the issue.

How do I change the 2nd drive to GPT (if possible) without losing the info I currently have on it (which is about 1.5 TB)?

Thanks

Win.10 won't boot after installing Win.7

Hi,

So i installed Win.10 via the UEFI and after installing Win.7 on Legacy Mode onto a different HDD i can't boot into Win.10 (I believe can only because Win.10 was installed via UEFI)

I tried installing the BCD Software but nope. I even tried to select my HDD but say Winload.exe error

Even tried going into the USB and try repairing but the same thing happens

 

Re-install xp in dual-boot configuration

I had an installation of xp . Then I added an installation of windows 7 and dual-booted both. Now the xp installation won`t boot and I want to repair / re-install it. If I do this , will it remove the windows 7 boot-loader and if it does then how do I get back my working dual-boot configuration ?
