Why does Grub boot 32 bit and 64 bit?
Grub must have some way of telling the kernel the bitlength, maybe it is in an associated file in /boot, looking into that tomorrow. The 32-bit and 64-bit kernels hash differently, but file reports them both to be x86. So I need to determine how to install the kernel to somewhere other than /boot so that the two kernels don’t clobber each other…
How to boot 32 bit and 64 bit Ubuntu?
The 32-bit and 64-bit kernels hash differently, but file reports them both to be x86. So I need to determine how to install the kernel to somewhere other than /boot so that the two kernels don’t clobber each other… Only mount /dev/sda1 on /boot for one partition, leave /boot for the other partition in place.
How to create a 64-bit kernel in Grub?
Note that this code has to be stored in a elf32 format and must contain the multiboot1-header. Also remember to set the text section to start at 0x100000 (-Ttext 0x100000) when linking your loader. Set up GRUB to boot your loader as a kernel in its own right, and your actual kernel as a module. Something like this in menu.lst:
Where can I find Grub files for i386?
The grub.cfg in the efi folder is manjaro specific. I386-Grub-efi Grub files for those with 32 bit efi systems attempting to boot a 64 bit OS. Grub files for those with 32 bit efi systems attempting to boot a 64 bit OS.
How to install a 32bit bootloader on a 64bit Ubuntu?
It has an Intel Atom Z3735F CPU. It is a 64bit processor but it only supports UEFI 32 bits, that makes it so none of the isos I have tried work directly to boot. The workaround for this was using the isorespin script on a Xubuntu-18.04-64bit image using the command: isorespin.sh -i xubuntu.iso -u –atom
Can you install Ubuntu on a 64bit processor?
I am trying to install Ubuntu in an Acer Aspire Switch10e windows tablet. It has an Intel Atom Z3735F CPU.

Is the root UUID set to / boot in grub.cfg?
The grub.cfg has the root UUID set to /boot for every entry. I know grub2 is all auto-generated and menus and jazz, but how do I just nuke all that and manually add entires (I’m not keeping this install long so there’s no worry about kernel updates)
