Ubuntu 21.10, error : you need to load the kernel first

cn flag

I'm new to Ubuntu and tried to make some partition space for installing Windows over it as dual boot. I think I've deleted some partitions that I shouldn't have, because I'm seeing these errors:

 error : no such device :036deeb3e26214f7.

 error : disk 'hd0,gpt3' not found.

 error : you need to load the kernel first.

Plz help

it depends on what you have deleted. Maybe you've totally removed Ubuntu.

You can always boot from a Windows installer

"*I randomly deleted something and now my computer does not work*" is, unfortunately, not specific enough to offer useful advice beyond: Reinstall everything. Next time, pay close attention to what you delete or change.

Install Windows first and then install Ubuntu in the same BIOS/UEFI mode as Windows.

Use the built-in GParted partition editor from an Ubuntu USB live session to create a single NTFS partition on the entire disk on which Ubuntu was installed for installing Windows.

Boot from the same Ubuntu live USB/DVD that you used to install Ubuntu. From the boot menu select Try Ubuntu without installing. Open the Disks application from the Dash, and make a note of the device name of the disk on which Ubuntu is installed. The device name has a form similar to /dev/sdX where X is a lower case letter. Open the GParted partition editor by clicking its icon in the Dash, and reformat the entire disk on which Ubuntu was installed to NTFS.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
