Always use the latest image (The March one has issues and should be removed)
I've never had a problem with the May image. Are you using the latest Win32diskimager? and formatting the SD card first? I tend to do that - format as NTFS and it all works fine.

After it boots () the upgrade should go without any issues.

The PC monitor is a known issue - especially if not native HDMI. I tried with a DVI -> HDMI connector and got nothing on the screen. I bought a HDMI monitor just for this (and other) reasons.

However, saying all that I have the i4 and you have the i1 (Which it is was never tested on - afaik). The only real difference is the memory but that shouldn't be an issue.

If you do get it to boot, can you post the output of xbmc.log and dmesg via pastebin - it will help in debugging.

Can you post the directory of /boot from the SD card and the output from uEnv.txt.

As a test can you tryone of the other distros, Archlinux, Android, Geexbox, Openelec and see if you can at least get it to boot.
