I've got Lenovo IdeaPad Y580 with a 64bit CPU and I would like to boot it from my external Toshiba HDD with a 32bit CentOS 6.4 installed on it. However all my tries ended up with kernel panic: not syncing. I thought it might be because of the UEFI, but it looks like it isn't... Has anyone got any ideas what might be wrong?

This question came from our site for system and network administrators.

Just install a 64 bit centos version. Why bother with 32 bit in first place? – timmeyh Mar 28 '13 at 12:16
Not it's not about UEFI, probably wrong disk, i.e sda vs sdb – warl0ck Mar 28 '13 at 13:36
If I wanted to install a 64 bit CentOS I wouldn't have asked the question. – Zeimer Mar 28 '13 at 16:51
at what point during the installation does it panic? – i.h4d35 Mar 28 '13 at 19:16
I'm not installing anything... I want to boot it from my external HDD that already has a CentOS 6.4 installed on it. – Zeimer Mar 29 '13 at 21:19
