Experts answer: Your question is very simple, no need to rush. You mainly for partition and delete partitions do not understand. Engage in a little chaos, to step by step to. First of all, is now a mess of the partition deleted. Best With the DOS-Fdisk. After running fdisk in DOS, NTFS file format is invisible, but it does not matter, mainly to see there is no other form of partition. There, one by one, from back to front all the deleted; If not, re-establishment of direct partition. Note that the input points District size, must use percentage (80G 15G hard drive is about 20%), do not enter a specific size. Because DOS does not support more than 10G partition. Sub End primary partition (C: drive) can be, regardless of the remaining space, after the machine restarts, re-use DOS's format command Format C: drive. Also, you said the loss of those spaces are lost can not. As long as the established C: drive on are looking back. Next, reinstall the system. In the installed system, the wizard will prompt you must be formatted for the NTFS format to install, then can be easily transformed into the original format, and then Tips can be installed by the system. Install a good system, then the system use the "Disk Management" to divide the other partition. System under the "Disk Management" can not partition the system disk (ie C: drive). If not, find someone with the DOS can help you. Up was hard to explain here.
