Disk Utility show WRONG hard drive size, No boot

Recommended Posts

Please help me:

 

1. I can only boot with DVD inside. Why?

2. My HDD is 250 Mb, I'm missing 100 GB (look down with red)

3. What is cylinders deal ?

 

I have windows and 10.4.5 on separate hard drives. Here is the info.

 

in knoppix:

command - sudo fdisk /dev/hda

 

The number of cylinders for this disk is set to 30401.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

 

command - p (print the partition table)

 

isk /dev/hda: 250.0 GB, 250059350016 bytes

255 heads, 63 sectors/track, 30401 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes
