I don't know. Did you get to the end of the installation the second time ?

However, if the grub boot loader is being called at boot you can enter 
the details manually.
Hit a key as grub starts (maybe up down arrow)
Press c for command prompt
Next bit really depends on how your PC is configured...enter commands
root (hd0,0)
   what does this say ?

kernel /vmli  and then hit tab, auto complete should show matching files 
names ?

initrd /init  and then hit tab, auto complete should show matching file 
name ?

boot

While the commands especially the root one will need to be changed for 
particular machines, either it'll boot or reply to the list with the 
messages shown...
