Acronis os selector 8.0 User Manual

• The first suitable active primary partition from the first hard disk is

looked for. If there is none then the first suitable primary partition is
looked for.

• Then the first suitable primary partitions of the rest hard disks are looked

for in a similar way.

• Then all the suitable logical partitions are looked for following the chain

on the first, then on the second, the third etc. hard disk.

• Then all the remaining primary partitions of the first, second etc. hard

disks are looked for.

Letter sequence in Windows 95 may differ slightly from that of the MS-DOS
7.0, if drives are connected to the computer that are partially visible or
completely invisible to BIOS. Letters to partitions on such devices will be
assigned after all the letters from MS-DOS 7.0.

2.9.2

MS-DOS 7.1/8.0, Windows 95 OSR2/98/ME

The order of letter assignment in these operating systems is similar to
previous ones with the following exceptions:

• Additional partition types are recognized: 11 (FAT32), 12 (FAT32 LBA)

and 13 (FAT16 LBA), resulting from FAT32 and large hard disk support.

• Additional partition type 15 (EXTENDED LBA) is recognized as a

reference to the next partition table.

FAT16 LBA, FAT32 LBA and Extended LBA partition types mean the same as FAT16,
FAT32 and Extended respectively, but additionally inform MS-DOS 7.1/8.0 that these

partitions should be accessed through BIOS extension.

2.9.3 OS/2

Letter assignment for this operating system is similar to that for MS-DOS 5.0
with the following exceptions:

• Partition status is ignored, i.e. on the first step the first suitable primary

partition is looked for.

• Partitions with type 7 (HPFS) are also looked for.
• All the primary partitions except the first ones are completely ignored.

2.9.4 Windows

NT/2000/XP

These systems differ from all the rest that use letters for disks, because it is
possible to change the letter that is assigned to a partition. Initial assignment
though is similar to that for MS-DOS 5.0–7.0 (for Windows NT 3.x) and for
MS-DOS 7.1/8.0 (for Windows NT 4.0, Windows 2000/XP). Windows NT 4.0
does not support the FAT32 file system but does assign letters to FAT32
partitions. One should also keep in mind that letter assignment for these
systems may differ heavily from that for other operating systems since it
