If it boots up to rommon> mode then the config-register is off
Post result of "show ver" and look at the config-register setting - should be 0x2102
If you are in enable mode, you should be able to delete the vlan.dat file

switch#delete flash:\vlan.dat

Which flash device are you trying to delete the vlan.dat file from?

I haven't deleted the file on a 4500 but based on this:

http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800c4546.shtml#reset_vlan

It looks like the command is:

"erase cat4000_flash:vlan.dat"

Try a "boot system flash <device>: filename in the configuration.

i.e.:

boot system flash slot0:cat4000-i5s-mz.122-20.bin

Do a show start and paste the boot system so we can see it. Also please post the results of a "dir" command for the device that the IOS is in.

No, you need to do a "show start" so we can see the boot system command.

Specify a boot environment variable
in the configuration and save the configuration

normally with a sequence of commands like
device# conf t
device(config)# boot system flash (filename here)
device(config)# ^Z
device# wr
Building configuration...
[OK]
device#

When done applying the boot options
type "show boot"  to see the boot path for next reload
verify proper file path with the  'dir flash:'

Like I said before. You need a boot system command in your startup-config:

=============
Try a "boot system flash <device>: filename in the configuration.

i.e.:

boot system flash slot0:cat4000-i5s-mz.122-20.bin
