NOTE: When new partition is created, initial 100MB is assigned as
boot partition by Windows OS.
Example:
If you make a partition of 40,960MB (40GB), usable space will be
40,960MB – 100MB = 40,860MB.
The partition size required for a system with an installed memory size of 1GB (1,024MB) and a full
installation of the operating system:
8,000MB + (1,024MB * 1.5) + (1,024MB + 300MB) + application size
= 10,860MB + application size.
If the provided partition size is smaller than that required to install the OS and paging file, expand
the partition size or utilize a larger disk. If your system does not have a sufficient dump file size,
divide the required file space into multiple disks by performing the steps below:
1.
Set the system partition size to a size sufficient to install the OS and paging file.
2.
See "Setting for Solving Problems" to write the debug information of the dump file onto
another disk.
If there is not enough disk space to write the debug information, add another disk for the dump file.
