Feedback from Hoary install

[Simon Turvey]

Hi,

Went to install Hoary on my laptop this morning.  Interesting 
experience.  Largely OK given non-standard install to external USB2 HDD. 
    Partitioning all went OK but installer definitely did not warn me 
before it stomped my Win2K MBR on the internal drive with GRUB.  Was not 
pleased.  Installer went for first reboot and GRUB came up and promptly 
went belly-up with error code 21 - whatever that is.

Anyway, any thoughts?
