What a coincidence I might say as yesterday I installed 4.9-R on QDI P61440BX/BIS(Intel BX chipset) mobo and got exactly the same thing, except I had chosen the second install a standard bootsector? which is what I normally choose, machine passed through bios just fine after installation, then immediate reboot after "updated ESCD successfully...", round and round in circles, I thought I had a hardware problem, the machine was gift and is destined to be a small samba server for one of the NGO's that I support. This is incidentally the 4th machine I have put 4.9 on in as many weeks, and is the first install I have ever had any problem with since 2.2.6. I followed the advice to reinsert the boot cd and go back to fdisk and press w, it worked perfectly when rebooted the next time.
