So I had antegros installed on my laptops hard drive, and it was customized the way I like it, so I prefer not to reinstall it. I had a USB stick with Linuxmint installed on it and I was adding Ubuntu to that USB to dual boot and went through that installation process. After it finished something changed in my hard drive because I can’t boot my computer without the USB plugged in, and when it is plugged in all I have are options for Linuxmint and Ubuntu. It just keeps booting and saying "no such device: 4cc1403b-5210-4b49-9a50-978b6d0dc973. Entering rescue mode."
Massive boot issue.
This issue can be caused by different situations… but as you say: when it is plugged in all I have are options for Linuxmint and Ubuntu You get this after installing Ubuntu to the usb-stick, so it is may related to this…
As i understand, you can only boot from this usb-stick and as you say both usb-installed system are working?
But when you unplug the usb-stick you get a Grub menu showing up, and it stops booting with the error:
"no such device: 4cc1403b-5210-4b49-9a50-978b6d0dc973. Entering rescue mode." ???
Question is here: do you press [F12] to get manual bootup menu and choose usb to boot?
Or you boot from internal HD-drive and get the grub menu with mint and ubuntu? But how do you get Antergos to boot to the error?
You can boot up with Antergos-Iso-Installer and rewrite Grub from this one like discribed here: (only for EFI-BIOS!!!)

In order from first to last picture:
Regular boot with USB inserted
F12 booted menu
All systems are working properly, I just can’t boot into Antegros even with the grub options, they turn more errors in themselves.
Hm but your pictures looks like that both grub menus are not the ANtergos ones and are genereated by Ubuntu and by Mint, two different grub installations? both on the usb-stick?
I do not get your setup clear here…
It is possible to fix this from LiveIso, or also from booting one of your OS that working, if the Antergos installation is untouched by any issues caused by Ubuntu installation…
@joekamprad I attempted that wiki you sent, but it didn’t work. I couldn’t get grub to install because it couldn’t find the root or something. But as of the moment my internet is down so I have to use my phone.
This can be linked to taht therev is something messed up with / (root) or simple caused by mounting the wrong partition to /mnt…
Personal setting yes they are all saved inside your /home/USERNAME/ folder…
Installed programs can be stored as a list to simple reinstall it, but if / (root) partition is not aviable anymore… no chance to generate that list.
For personal settings i would copy them one by one back to not make a mess…
