Installing from an MS-DOS Partition:
Assuming : D is CDROM
Code:
C:\> md c:\freebsd
C:\> xcopy d:\bin c:\freebsd\bin\ /s
C:\> xcopy d:\manpages c:\freebsd\manpages\ /s
.
.
.
From Choose Installation Media Menu choose number 5 : DOS
and follow the process
For CD/DVD Problem Try another Internal Driver, Especially SATA,
Or a Pioneer One
I had this problem, changing DVD Driver solve it
