I want to install Ubuntu on a 8 GB flash drive

I facing problem I enter to bios to go to the flash after that to boot to ubuntu to install it I faced that

There is two options

-install ubuntu (notworking)

-safe graphics

Just safe graphics works

But install ubuntu not working

I think because the flash 8 gb they need more I think right??

While I install the ubuntu it become black screen I think the size that why opreating system not working

You need to partition and format the flash drive if you are going to install Ubuntu on it.
Make the same partitions you would on a hard disk
eg

  • esp partition 512Mb fat32
  • linux root filesystem partition ext4 all unused space

8Gb should be enough space, unless you want to write a lot of user data to the flash drive.
16Gb would be better, and you should use a usb3 flash drive and socket.

I think I will try usb 16 gb a

The installer can do that in the background if you accept the defaults…

I’d imagine 8 GB is just too small for Ubuntu… I wouldn’t even consider less than 32 GB…

So I think I will change it to32 Gb usb

I think you’d better go with an external SSD or HDD at least.
Pendrives are not ideal for running an OS, as it involves a lot of writing.
The OS will run sloooow on a pendrive, and the pendrive is going to fail much sooner than with normal use.
Or at least try to use F2FS.
But I vote for external drive, not a pendrive…

I got it thank you for helping really !!!

I will have the flash and download ubuntu on virtual machine after that to make my flash on fsf2 I need commands for terminal and thats it

I change my usb to fsf2 congurlations !!

After that I will install on ubuntu on it

Thank I love foss community​:heart_eyes::relieved:

Be aware that while grub2 supports f2fs, there may be issues with booting,

https://wiki.archlinux.org/title/F2FS

How do I know,

I am not sure, I have not used f2fs.
I read that grub may not be able to find the files it needs in /boot.
Try it and see what happens… Linux is all about being able to experiment with things.

I will learn dual boot ubuntu and windows 11

On usb 8 gb

And making shrink 50 Gb for ubuntu

And disable the bitlocker

And thats it we did it

And any issue facing I will search about it

Interesting - F2FS looks ideal for things like RPi - but - Raspbian just defaults to ext4 for root “/” whether booting off external USB 3 or locally off SD-Card…

Note : I run 2 x Pi4 and 1 x Pi5 off external USB 3 SSD (the Pi5 is running Ubuntu 24.04 for arm64).

I have a pair of Pi Zero 2W and a Pi3B running on SD-Card…
