Talaat Etman's questions

Some users realize that they boot directly to Windows after installing Ubuntu. Also some users have to install Windows after Ubuntu, but this affects the loss of the grub bootloader. When the USB flash drive is lost or corrupted they can't go back to an Ubuntu live session or Ubuntu partition.

Now we have to reach Ubuntu from Windows, but the problem is that Windows prevents us from adding Ubuntu to the boot menu. In addition, Windows can't read the Linux based partitions, and doesn't help to boot from an Ubuntu ISO file.

Most guides recommend using EasyBCD to add the Ubuntu partition to the Windows boot menu, but this doesn't work anymore with the new Ubuntu releases.

For recovery purposes and for dual boot users, it is important to add an Ubuntu live session and or Ubuntu partition to the Windows Boot Manager.

The question is how to boot with Ubuntu from the Windows boot menu?

Update:

The aim is boot by Ubuntu Live Session from squashfs file and Ubuntu partition, this makes difference from other questions existed or suggested. Ubuntu 24.04 desktop version and Windows 11 23h2 are used in bios based device. thanks for sharing your experience.

The situation:

I enhanced the firmware-b43-installer package to include b43-fwcutter, my wifi driver, the wireless network name, and password. After installing this improved package, whether in a new installation or live session, I can directly access the Internet.

Befor this modification, the firmware-b43-installer package requires an Internet connection to download the b43 wifi diver file in a compressed form from its source. It also requires a package to unzip this compressed file and b43-fwcutter package to install the driver.

The question:

Is it legal to improve or change one of Ubuntu .deb packages related to an driver installation for personal use on my devices?

The problem:

The USB flash drive takes alot of time to install grub bootloader, now the grub bootloader is installed in the MBR, but the /boot/grub/* files may be missed or corrupted or deleted acdently, and may be a solution that is used as useful way without the need to reinstall the bootloader.

The aim:

Regenerate /boot/grub/* files.

The question:

What are the commands needed to regenerate /boot/grub/i386-pc/* files and /boot/grub/grubenv except grub.cfg file in a fatest fashion?

I encountered an issue while attempting to install Ubuntu via live USB. The graphical installer did not offer the option to choose manual partitioning. Even when I selected the empty partition, the installer showed an empty partition list. I also faced a similar situation while selecting the hard drive to install the bootloader. As a result, I had to install Ubuntu 24 alongside another previously installed version of Ubuntu.
Can Ubuntu 24 be installed on an empty partition using minimal.squashfs through the terminal?
