Re: [RFC] Allow separate boot block and core.img location?

Isn't this as simple as:

grub-install /dev/sda
dd if=/dev/sda of=/dev/sda1 bs=512 count=1
followed by restoring DOS MBR... ?

Cheers!

Subject: [RFC] Allow separate boot block and core.img location?

 

There are many users using dual boot with Windows and Linux. In this 
configuration installing grub in MBR unfortunately breaks at least some 
updates of Windows 8 (update fails). And installing grub in partition 
has all sort of known problems with blocklists. 

What about allowing separate locations for boot block and core.img? 
I.e. something like 

grub-install --boot-block-location=/dev/sda1 
--core-img-location=/dev/sda 

This has all advantages of embedding core.img while allowing leaving 
MBR alone. Actually we could assume default --core-img-location, meaning 
that for 

grub-install --boot-block-location=/dev/sda1 

we assume that core.img has to be embedded in /dev/sda unless proved 
otherwise :)
