I've Just upgraded to DD10 and installed Operating System Selector, since then when I try to reboot I get the usual message "press esc or F6 etc.," to continue. Neither of the commands works and I can get nowhere! My only way forward if to boot the system from a floppy with Windows 95 on it and use the command "fdisk /mbr", I can then boot into Windows XP. When I next reboot I am back where I started from! Also I cannot boot from a CD so I cannot use the rescue panel on my XP installation disk to effect repairs. Any help most appreciated.
