Trouble Dualbooting WIndows 10 and Parrot OS

Hey guys, so I had this setup before on my previous laptop, but on my Dell XPS 9370 it is proving to be troublesome. I am trying to have the Debian-based Parrot Security 4.1 distro dualboot alongside Windows 10, and after messing with some BIOS settings (I had to turn SecureBoot off before I could even load the liveUSB) I successfully installed Parrot OS. The trouble that I'm having now is that Windows won't boot. I have the GRUB screen option for Windows available, but when I choose it I am directed to a screen asking for my Bitlocker key. After giving it the correct key it tries to boot but throws a "inaccessible_boot_device" error.

This has been a huge headache so I'd appreciate it if any more knowledgeable members can lend a hand. I am using UEFI for both and can provide more info if necessary.

The cheeky, Aussie side of me would say that a loss? ;)

Hi @dystope and welcome to :)

I run about 45 Linux side by side on a Toshiba Satellite and I have only just put 4.1 on a couple of days ago, after an absence of a year or more, so there are a few changes I notice.

I don't have Windows to compare with, and others will help there, but I have a few ideas.

I found it a royal PITA to get Parrot on (& I am all UEFI/GPT), and the loading of the bootloader kept falling over. I went to Parrot's site and if I may ask, did your Live Medium initial menu have a long list which ended with GTK Installer, and which option did you choose? In the end, I used the GTK and it installed fine.

If you want to go back to starters, you could remove Linux entirely, and use this as a guide

... then go with the Parrot again. If you use that article, skip the WUBI reference and start at Step 1.

Others may have some good ideas.

Good luck :)
