In some specific situations, you may want to backup only one partition but still wish to boot it as a disk image.
\nLets see below how to turn a partition image into a disk image.<\/p>\n

Before we start, have a a look at the below disk layout to have a better understanding of items such as MBR, BS, Disk and Partition.
\n<\/a><\/p>\n

1.Create a 1 MBytes (2048*512=1MB) header file (under virtualdisk, create raw disk image)<\/strong>
\nNote : instead of 2048 sectors, you can go for 63 or 128 or whatever \u00ab\u00a0sectors before\u00a0\u00bb may suit you – just report that number in the following steps.
\n<\/a><\/p>\n

2.Append this header to your partition image using the dos command line copy \/b header.img+part.img disk.img<\/strong>
\n<\/a><\/p>\n

3.Adapt MBR type=07 (for ntfs), boot=80, chs start & end=1023*254*63, sectors before=2048, sectors=bootsector.totalsec+1<\/strong>
\n(You need to untick \u00ab\u00a0hide advanced menu\u00a0\u00bb under tools menu to enable advanced screens in CloneDisk).
\n<\/a><\/p>\n

4.Inject boot code (nt6) (this will also fix the mbr magic byte AA55).<\/strong>
\n<\/a><\/p>\n

5.Adapt bootSector hiddensec=2048 so that it matches MBR sectors before field<\/strong>
\n<\/a><\/p>\n

You are now ready to boot this image as it has all it requires to boot :
\n-a disk boot record
\n-a partition table
\n-a boot sector
\n-a consistent BPB (bios parameter block)<\/p>\n","protected":false},"excerpt":{"rendered":"
