I used VirtualBox to set up a small Arch Linux 64 bit x86 machine. Everything is running fine installed on the 8GB big virutal hard disk in the VMDK format.
cfdisk shows that I created two partitions:
- Type: Primary, Type: Linux (ext4), Bootable, First Partition, Size: 7.5G
- Type: Primary, Type: Swap, Solaris, Bootable, Second Partition, Size: 0.5G
I heavily customized Arch Linux and now want to make real bootable media out of it.
1. How could I create a bootable media without the complicated archiso installation process, but directly using a drive image that I create somehow?
In fact, I tried already creating my bootable media. I used Ubuntu to convert my
/dev/sdc using the command
qemu-img convert os.vmdk -O raw /dev/sdc
Once completed, I rebooted to the PC's boot menu but the pendrive was not showing up. I turned off secure boot and enabled
Legace Boot Support. Nothing helped. Hence, I entered the Grub command line of my Ubuntu installation and entered
set root=(hd1,msdos2) # hd1 is my usb stick, msdos1 is swap, msdos2 is bootable configfile /boot/grub/grub.cfg # in order to load the usb's grub
2. Some strange things happened then
- I put the stick into my laptop -> USB 2.0 port (I have got a USB 3.0 stick) -> Booting... -> Graphical Arch Linux Splash Screen -> Emergency Shell stating something like
Can't run fsck. Error: Can't find drive with UUID=...(However, the UUID is absolutely correct. I changed that on Ubuntu and within Arch itself in /etc/fstab! When I do
blkidon the emergency shell, the USB drive is simply not there. Instead I get my internal SSD on /dev/sda. I even do not find any usb drive in /dev/* and dmesg states nothing as well!)
- I put the stick into my laptop -> USB 3.0 port -> The grub command line is not detecting the drive. There is only
hd1. However I sometimes boot from my external hard drive connected via usb 3 using the bios boot menu.
- I put the stick into my workstation PC on a USB 3.0 port -> Not in BIOS boot menu, started via grub and
configfilecommand -> It booted whereas it did not boot on the USB 3.0 port on my laptop -> and then the same emergency shell as in
- I put the stick into my workstation PC on a USB 2.0 port -> Started via GRUB -> It boots successfully without any issues.
I have no clue, what I should do!? I basically just want to make an image out of my existing virtual Arch Linux that I can transfer to any device by simply copying it without a complicated Arch install.
Any help is appreciated.
