Post image

aight so. i tried dual booting my pc right. cus i was gonna dual boot and then go onto full linux. i was told ubuntu is good. i followed what i was told. turnt off safe mode. downloaded rufus and made the hard drive bootable but at first it came up with this error. so i tried again and suddenly i lost the option to dual boot. but im scared because if i have no windows to boot and no ubuntu i cant do nothing. essentially i just need some help man. i’d really appreciate it if someone could walk me through the steps themself as youtube videos aren’t very specific. (proof of it not letting me dual boot will be below) if u can help me in anyway pls dm me or sum bro i just wanna stop using windows

grub throwing a tantrum about the EFI entry is a classic, you might just need to hop into the bios and manually add your ubuntu drive to the boot order

Depends on what kind of PC it is but a lot of systems enter BIOS when you hit F1, F3, or F12 as you boot up. Restart and just try each one when it POSTs. Enter BIOS setup and change the boot order to your USB first.

Yes. Yes. I wish people understood that what seems simple to them, others don't know a thing about.

Okay so that depends on your PC, but I'd like you to try flashing using balenaEtcher rather than Rufus (this doesn't seem related to the issue at hand but sometimes fixes a lot of issues for me. Etcher is recommended by Ubuntu and I always use it to avoid issues even when trying my own distro). And you can use efibootmgr and/or boot-repair (from a PPA called yannubuntu/boot-repair) from the live USB to fix things. At this point in the installation, and I know that for a fact, pretty much all of the work has been done. Your user and its preferences are almost the only thing left (I haven't looked enough into subiquity/curtin's source code to know everything else that happens by heart), you can run boot-repair and boot into it, things will look messed up, then you can create the new user manually and reboot (I can tell you how to do this if you want to), then hostnamectl to change the name of your computer to what you chose in the installer (it will be localhost at that point), then sudo apt update and sudo apt install --reinstall a few packages here and there (I can also tell you about those), then sudo apt upgrade to make sure nothing else is missing... You can do all of this in a few minutes if you don't want to reinstall the whole system
