My windows partition disappeared after resizing it. Found a post with a walkthrough for how to fix it.

Did everything and this is what I got in my terminal.

Enter an MBR hex code (default AF): 07

Set the bootable flag? (Y/N): y

Unused partition space(s) found. Use one to protect more partitions? (Y/N): n

Recovery/transformation command (? for help): o

Disk size is 490234752 sectors (233.8 GiB)

MBR disk identifier: 0x0566FE4C

MBR partitions:

Number Boot Start Sector End Sector Status Code

2 * 133448880 489972567 primary 0x07

Recovery/transformation command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

PARTITIONS!!

Do you want to proceed? (Y/N): y

OK; writing new GUID partition table (GPT) to /dev/disk0.

Warning: Devices opened with shared lock will not have their

partition table automatically reloaded!

Unable to open device '/dev/disk0' for writing! Errno is 1! Aborting write!

Recovery/transformation command (? for help):

The problem is the second to last line, says the action was aborted because the disk cannot be opened. No idea how the **** this is a problem. Help please.
