ubuntu bootloader?

Question

linux

after installing ubuntu, it doesn’t boot, but enters the bios,
tried different options in the bios,
tried loading ubuntu from a USB flash drive and restoring the loader, and did many other variations that I found on the Internet,
but still
, can there be such an image of ubuntu so that the bootloader can be fixed right away?
or what to do?
Thank you

Answer 1

the image apparently became crooked
after 5 reinstallations, everything became normal
thanks to everyone

Answer 2

On some systems, an automatic transition to the BIOS is carried out if no disk was found or the bootloader was not found.
Yes, you have a problem with installing the bootloader (and this is visible during installation because it is an error) or a problem with setting the setup order in BIOS.
At the moment it is not clear whether you have UEFI or Legacy configured in BIOS and, in principle, it is not clear.
Check boot settings in BIOS.
There is only one image of UBUNTU that is worth using - off. site.

Answer 3

Ubuntu cannot enter bios, bios comes first, then the OS loader (grub), and only then ubuntu.

Answer 4

Usually, if no device is found that can be booted from, the BIOS hangs stupidly, showing a message like "Insert a device that can be booted from", but theoretically, if there are no such devices, it can enter the settings - it's true that such hardware is not alive saw.
Bubunta, as well as Windows, and FreeBSD ... and even MS-DOS have nothing to do with the bootloader. Yes, each of them has software that rewrites it - but if it doesn’t boot after installation, you need to carefully study the BIOS options - I had a case when, after installing VmWare, it didn’t boot until UEFI was disabled in the BIOS
