Using grub-setup is discouraged as grub-install calls it if needed anyway.
LOCAD ISO IN RAM GRUB2 HOW TO
To find out how to boot your usb directly into VirtualBox with a Linux host see the bottom of this post.

It's very documented if you don't know as I don't since I only use Linux, except for Windows in a VirtualBox machine. Please change what is needed if you are installing grub4dos from Windows. The grub4dos will not overwrite any grub2 files in /boot/grub/, only add new ones. Please make sure you are on the grub4dos machine now and not installing grub2 again.

Which is good.Īfter this we have the proper /boot/grub/ on the usb device, next we install grub4dos from Windows or whatever Linux you have grub4dos compiled on. When /bin/true is specified it will 'do nothing successfully' when executed instead of overwriting the master boot record. I found that by using the command above we can generate all the necessary files including core.img without actually touching the mbr.
NOTE: It is not required (as I once thought) to actually install grub2 to the mbr and then grub4dos over it. Grub-install -no-floppy -root-directory=/mnt/usb/ -grub-setup=/bin/true /dev/sdb Next use grub-install to create the grub2 core.img and other files we need on the mounted usb drive using the command below. Boot into a running system with grub2 or compile it (download the latest 1.9x version from and install like I did. There is probably a way around this though I just haven't had the time though you are more than welcome to find a way and I would be happy to know the answer. It's unnecessary and actually will cause problems.ģ) Adding the Grub2 font console coloring in grub.cfg seems to intercept loading the background image. I would constantly get an "unknown filesystem type" and be dropped in to the grub2 rescue-shell which is very limited.Ģ) Do not install grub2 onto the actual partition of the device or the mbr.
I actually did this by mistake and was not able to get grub2 to boot from my usb until I reformatted the partition with a new dos partition table. This was the outcome of scouring many docs about installing and discussions about the limitations I was dealing with.Īs a note this was all done on an 8GB flash drive using Slackware Linux.ġ) Do not install grub4dos to the first partition on the device, only to the mbr. Even though the latest beta UBCD iso supports the loop boot in grub2 I wanted to have a system I could modify such as updating the virus databases and many different tools available in UBCD. I started this to be able to boot all of what I wanted from grub2, yet I also liked Ultimate Boot CD, though did not want to edit the many menu files to convert them to grub2, that are installed with it. So now we can even load Grub4Dos from Grub2! I got memdisk from /usr/lib/syslinux and placed it in my usb's /boot/grub/ directory. If you compiled from source and don't have grub.exe or simply prefer to use memdisk,Īll that needs to be done is to use memdisk from syslinux as the kernel like this

If using the files from the grub4dos zip which include grub.exe If you would like some very good information on more than is my scope at the moment please find the links at the bottom of this post.ġ) Grub2 is able to load Grub4Dos grldr without a patch! Also including my example grub.cfg and menu.lst files including many unique distros which we haven't had much guidance on booting with grub2. This is a non-distro specific instruction on how to load Grub2 from Grub4Dos and to add background images into Grub2.
