Need help making Windows bootable after installing Linux I used this questions's answer to install Linux(I installed Mint, however, not Ubuntu) and followed along.

I do believe I didn't follow the answer properly, as I still have a placeholder partition unused, but Linux installed and works perfectly. I did have to use the diskutil resizevolume disk0s2 140G 3 jhfs+ part1 800M jhfs+ part2 200M jhfs+ part3 200 command differently as I am on High Sierra, and I have APFS containers. I gave 4GB for Linux Swap

Linux Mint works perfectly, but when trying to boot into Windows via the option boot menu(on startup), the built-in boot manager freezes. If Windows is set to the default startup drive, I get a blank screen.

The Bootcamp partition has next to no important information, I can format/reinstall it if necessary.

The following is my diskutil list output. BaseQi is a exFAT 64GB SD Card.
