Cant access harddrive in ms-dos

im installing dragon linux and i needed to do this in dos so i got a boot disk and i got on dos and i cant access my hard drive ive tried all the commands my harddrive is workingfine in windows

At the DOS prompt,A:\> C:,then hit enter. Prompt should change to C:\> . Being not familar to Linux,at thia point your C drive commands should be accessable. If not ,change drive back to A and try "A:\> [enter commands without the brackets] C" then enter. Let me know how you make out. Try www.bootdisk.com for a Linux bootdiskfor DOS.

If you had your C: partition NTFS formmated
you may need to format format C:
Or fdisk and repartition
