Re: Grub rescue problem

As I see it at this time, if he keeps trying to use the 64 bit Mint installer, since it may detect a left over backup of GPT at end of drive, he'd be better off using a 32 bit version of Mint for the install. It wouldn't deal with that backup GPT at end of drive, but it would avoid it, probably not see it at all. I'm not sure there's a way to remove it short of what I've done in past using dd command to over write the ending sectors of a hard drive. Maybe some safe utility that I'm not aware of can do that, without messing up entire drive. Although I could give the OP instruction line on using the dd, I'd really rather not take that route, it has too much risk of losing his windows. I do remember windows had some safe convert programs for doing that, changing around GPT and MBR, and reconfiguring extra partitions from GPT into an extended partition under MBR. Not seen that in Linux, but may exist and I'm not aware of it.

Spearmint2, is there a way to force Mint live USB to boot in legacy BIOS only mode or create a Mint live USB for legacy BIOS only? Did a lot of searches and cannot find anything definitive on this, just how to confirm if Mint was booted in UEFI or legacy BIOS mode. One of the issue here is Mint installer insisting on UEFI installation.
He'd need to use what he has I guess the UEFI + Legacy setting in the BIOS, and install 32 bit Mint version. Seems the person who originally put the SSD in, did that to make it msdos MBR partition install of windows 7, but the SSD had come as GPT, but would have expected it to come RAW. Maybe the original owner had win7, upgraded to Win10, didn't like it, went back to win7, which put in the current MBR, killing the front GPT, but failing to remove the backup GPT section at the end of the drive. I'm just guessing, but it's definitely MBR now and not GPT.

His future approach? If he still wants to use W7 in future, and manages to find a retail box version cheaply, and some should soon be coming onto EBay with end of W7 support, is then for him to completely redo the drive, install 64 bit Linux Mint, and install W7 into a virtual box inside of Mint and use it that way for whatever he needs to use windows for. That's what I did, but rarely go there anymore.

Screen shot from MSI H81M-E33 page https://us.msi.com/Motherboard/H81M-E33/ and initial firmware release is UEFI. Apparently, there is no legacy BIOS only mode on this mobo.

I had checked these pages and even the data sheet didn't mention UEFI. I can see on your link, when you get into the details that's revealed. Seems they'd put that in the specifications listed to, instead of "4 click BIOS".

MSI does have weird documentation down to a science, that is why I did the screen shot. Took me a while to find the UEFI information too.
Mint Mate 19.1. Main rig is HP 800G2 I5 6500 16GB ram, 120GB boot drive, 2x3TB, 1x4TB data drives. Oldest rig is Mate 18.3 on Dell D620 with 32bits core duo.

I can definitely try installing a 32 bit version. Does it make any difference when using Cinnamon vs. Mate vs. Xfce?

MATE is considered the most stable and midrange demand, Cinnamon most pretty but more demanding, XFCE the least demanding. Any of them should do.

You, sir, are a genius! Installing in the 32 bit version allowed the bios to recognize windows 7 and I was able to install Mint alongside Win 7. Thank you for the advice!

Updating the title now.
