Prepare a grub.cfg and put into /boot/grub

Once done, you’ll have “EFI” directory to store EFI binaries for boot, and “boot” directory to store grub. Sudo grub-install –target=i386-efi –efi-directory= –boot-directory=/boot –removable /dev/sd Sudo grub-install –target=x86_64-efi –efi-directory= –boot-directory=/boot –removable /dev/sdX Sudo grub-install –target=i386-pc –boot-directory=/boot –removable /dev/sdX If necessary, create additional partitions. Use fdisk to create FAT32 partition and mark as bootable. Since legacy mode doens’t recognize GPT diskĢ. You could use exFAT or NTFS as the data partition.ġ.

If you have large files above 4G, consider seperating the boot partition with data partition. To use grub2 as the universal USB drive bootloader, you have to install grub bios/uefi on FAT32 partition. Thus, only FAT32/EFI System Partition stores EFI binary could be booted. According to UEFI spec, it requirest an “EFI System Partition” which “happens” to be compatible with FAT32 and says to assign it a GPT partition type of C12A7328-F81F-11D2-BA4B-00A0C93EC93B and an MBR partition ID of 0圎F. In order to boot both BIOS and UEFI machine, the USB should be partitioned compatible to both boot loader. This article introduce the pure manual way to customize your own installer ISO. There already some user friendly tools to customize all installer, like WinUSB. However due to the implementation of Windows’ bootloader, it requires some manual modification to Windows ISO files. If I try to boot this USB HDD LILO still comes up, or partially comes up, but of course it's not configured to boot openSuse.GRUB2 is very powerful to act as the universal bootloader on a USB driver to install OS from. I tried running Super Grub Disk to overwrite LILO and install GRUB but it either did not work or I did not know how to use it properly.probably the latter. OpenSuse recognized all my drives and the installation went pretty smooth except for the installation of the boot loader. However, VL would never startup properly so I then tried installing OpenSuse. I then successfully installed Vector Linux to the USB HDD and was able to write LILO to the MBR on this drive. Both of these OS's would not recognize my SATA HDD or USB HDD configurations on this PC. Prior to this installation I was unsuccessful in trying to install Ubuntu 8.04.1 and Fedora 9. So.I just chose to install GRUB to the root partition instead. The only option to install grub to the MBR was to use 'sda1' which was my primary windows HDD. However, during the installation setup, I could not figure out how to install GRUB to the MBR of my USB drive 'sdb1'. I seemed to successfully install OpenSuse 11.0 on my HP Personal Media Drive. I have Windows XP installed on the primary SATA HDD. I have an HP Media Centre PC m7170n with an ASUS P5LP-LE motherboard that allows me to boot from any USB port including my 500GB USB HP Personal Media Drive.
