If your harddisk is full, you cannot create another partition. You need to format the old one and install it in newly formatted partition. (warning! All data on the formatted partition will lost!) But move out all important data before doing so.

 

Thank you.

You said another two partition,did you use those two? But 14.75GB + 200mb is not enough for windows 8. It needs at least 16- 20GB. How large of your c and d drive?

Thank you.

You don't say if you have any data in the two partitions other than C: and D:, nor do you say how much total spare capacity you have, but if you move any data out of these two partitions, even if only temporarily, you could merge the two to give you three 'drives' - C:, D, and one of 215 Gb. The 14.75 Gb partition is of little use to man or beast ! Presumably this partition would be drive E:.

 

You can then decide, depending on how much spare space you have in C: and D;, whether to devote the whole of this partition to Win 8 or to split it into two more realistic sized partitions and still not exceed the four partition limit. To pull numbers out of thin air, two partitions of say 100 and 115 Gb would be more useful than what you have at the moment.

 

As you are probably well aware, the disc management tools under 'Computer' are sufficient for this task. Just one safety tip - back up your important data before you start doing this !

I can not put any data in the the 200mb and 14.75gb partitions because they are hidden and i only see them @ disk management where they are not assigned any letters and can not be deleted.  C: is 421gb capacity, 249gb free  and windows partition. and D: is 28.9gb capacity,  26.8gb free  - this has drivers and is used for onekey rescue system... will putting the os in D: be of any harm to my pc and will i be able to use the rescue feature after this..

 

Thank u :bananas:

My apologies !  I misread your OP - I mistook your 200Mb for 200Gb !

 

The 200 Mb partition is used and required by your Win 7 installation, and I would not change your recovery partition since this would almost certainly affect your chances of doing a successful recovery in the future, should you need to. It might be worth your while checking the Lenovo manual or their support section to see if you can convert the recovery to DVDs.

 

What you can do is add the odd 14.75 Gb to your present C: drive - delete the partition representing this quantity, then increase C: by that amount. You would then have about 260 Gb free in C:. You could then create a fourth partition of say 50 to 100Gb by taking this space from C:.

 

You would then have 200MB - Windows; 335 GB - C: ; 29 Gb - D: ; and 100 Gb - E: for Win 8, if my mental arithmetic is up to it.

 

But before you do any of this - BACK UP YOUR DATA !
