I just bought this laptop: http://h10025.www1.hp.com/ewfrf/wc/d...roduct=3860190

and it's supposed to have 320 GB HD but It only shows 298.1 GB. I'm already having trouble installing Windows 7 I keep getting the Missing BOOTMGR message but know I'm using KILLDISK and it only shows 298.1 GB. It is a refurbished laptop so maybe that's why. It came with Vista but when I tried to format and instal W7 I keep getting BSOD and BOOTMGR message. If anyone can help it will be greatly appreciated

That is normal. It is the difference in the way megabytes are counted by the hdd manufacturer's and the way os's count them.

Perfectly normal. The advertised space is always higher than the actual usable space.
My 500GB shows up as 465GB.
My 640GB shows up as 596GB.

It is not just in the way MB are counted. It is in the way every prefix is counted.

In base 10 they use 1,000. Example 1,000bytes is a Kilobyte, 1,000Kilobytes is a Megabytes, 1,000Megabytes is a Gigbyte?

Bianary counts 1,024 bytes as a Kilobyte, 1024KB is a MB, 1,024MB is a GB?

Using spaceballs 500GB which is base 10 reports 465GB base 2. Remember they both are the same number of bytes.

5000000000bytes/1024=48828KB's/1024=4768MB's/1024=4.6566GB's

Same formula /10=500GB's.

Other problem sorry can't help.

as others have already said has to do with the difference between a gigabit and gigabyte. Rule of thumb is take the advertised space and multiply by .93

windows can't detect all the space
