Removed OCLP but can no longer boot into Windows!?

Hi all,

On my 2015 MBP I had Monterey installed along with Windows 11. However I tried Sequoia and had issues booting occasionally with higher cpu temps. So I followed the instructions on OCLP’s site and removed the bootloader and reinstalled Monterey.

However, I can no longer boot into windows at all. The option is there on start up but it boots into Monterey.

Can anyone help or give me some advice how to rectify this?

Thanks!
