I had originally tried to install 10.5.2 rev 1 with no success.
Tried Rev 2, had a successful install.
Only problem is When I try to boot using the MBR and EasyBCD, i get
"Chain boot error _".

I selected the dual boot option in the Leo install and went into Vista to put an entry in EasyBCD.

I am stumped. Any suggestions?

I have an ACER Aspire 5050:
AMD Turion™ 64 Mobile Technology MK-38 (512KB L2 cache, 2.2GHz);
4GB (2/2) DDR2 667 SDRAM;
120GB hard drive;
integrated Super-Multi drive (DVD+R, DVD-R, DVD-RAM);
integrated ATI Radeon™ Xpress 1100 graphics;
