pipeline find results to root

[Marcos Reyes]

Hi, please keep in mind that I am a complete Linux newbie.  I was going to try out a few distros with YUMI (Let's you multi-boot OS installers or utilities from a USB drive).  YUMI puts all the OS installers on the same partition.  One limitation of YUMI is that you can't have both Windows and Ubuntu OS installers.  The work-around is to rename the "sources" directory belonging to Windows, which allows the Ubuntu installer to work.  I thought a good solution would be to put them on different partitions.  So here is my question:

Is it possible to pipeline the find result to the root command, so that you can boot from a different partition on the USB drive.  I got the inspiration from reading on the web, where someone describes how to recover after Windows fucks up the MBR.

grub>find /boot/grub/core.img
grub>root (hdx,y)   (previous command will output the x,y)
grub>kernel /boot/grub/core.img
grub>boot

Thanks,  Marcos
