I'm obviously very stupid, but fedora is polite about it, suggesting it might be a bug. My laptop has 4Gig of ram, twin turion. Of dev/sda1 - sda10 I give it
sda5 = /boot (40/80M used)
sda6 = / (Old fedora install 5G of 19G used)
sda7 = /home (9G of 23G used)
which is the previous arrangement on fedora 9. Next screen is about a boot loader, and it offers me sda1 or sda6. I tell it go go and play in the traffic and uncheck the box 'install boot loader' I hit 'next' and it crashes, muttering about some python assertation. It offers to save the error, and I say yes, but doesn't - it just saves some other crap.

Any ideas, Fedora experts? I'm afraid I'm rusty on fedora, having defected to slackware & slamd64. But I am trying to get back.

I'm not sure that you can upgrade from F9 to F12. There is documentation about upgrading from F10 to F12, so perhaps your first move might be upgrade to F10 (or just a clean install). http://http://docs.fedoraproject.org...grade-x86.html

The link didn't open here, but thanks for that idea.

I'll clear off the install. Mebbe then. I actually hate reinstalls with a passion, because I end up farting about for days trying to settle things as I like them. But some things must be done.

Oh sorry about my terrible skills at inserting a hyperlink. Seems I had a double http :-/

Try this http://docs.fedoraproject.org/instal...grade-x86.html

do a fresh install after reformatting the WHOLE drive to a blank disk
let the fedora 12 installer reformat it to ext4 ( fedora 9 was ext3)
and reformat the /boot partition ( the newer fedora versions use a different boot format )

Is the bit about the /boot partition totally necessary? It's an awful PITA because I have slackware and a basically defunct vista install as well.

then just chainload from slac

Thanks folks for all your answers.

Life has backed up on me, so I'll mark this closed, file the advice, and get back to it when I can.
