Re: Partition Table keeps becoming unbootable

The image below shows the initial TestDisk screen when I choose the disk. It appears to be showing everything correct now. These are the 5 partitions I saw that you have already explained. I understand the logical and extended partitions now.Fiona wrote:Which partition was your wrong bootable partition?During one of the non-boots, I went into the command prompt again to run Testdisk. The initial result before analyzing the disk shows the wrong drive as bootable, but also shows 5 partitions. The wrong bootable partition, the boot as primary, the third partition as primary, a fourth partition as LBA which I didn't set up and a 5th partition as logical. Then I analyze and it finds only the four but also with the wrong drive bootable. I've fixed them and saved them but they always move back.
Is that what is happening in the image below? Once I click quick search, I get this screen.Fiona wrote:Some computer manufacturer are modifying the MBR to let you start into a system recovery to get back to factory settings using a certain key during startup (manual and BIOS message can help).
It's like a bootmanager.
The "Vista Partition" (which is the recovery partition) is marked as bootable and my Windows partition is not.
It's possible. I did a sector by sector clone. Would that do it?Fiona wrote:Would it be possible that you cloned a modified MBR?I finally replaced the disk and cloned the information to the new, larger disk sector-by-sector using Acronis True Image.
There is no virus protection in the BIOS.Fiona wrote:Some Info about the MBR:
Partition table only contain your partitions and is a part of your MBR.
The MBR also contains your bootloader 446 Byte (64Byte is your partition table and 2 Bytes a signatur that your MBR is valid).
MBR is a single sector and the size is 512 Byte.
Did you check your BIOS for any MBR protection like Virus Protection?
It could prevent any changes to your MBR.
There are no disk or controller events logged in the System log.Fiona wrote:Also watch your eventviewer and windows logs for some entries under system like disk or controller.
I've corrected the boot partition in the second image and written them to the table. I went back into the Quick Search in TestDisk and the screen is exactly the same. The Vista Partition is selected to be the boot disk.
I've been having problems with my BIOS (yes I've flashed it to the most current version) changing hard disk priority from the SATA disk to the IDE disk. It also adds USB devices as Floppies and Hard Disks. But that does not coincide with the problem I'm having. Do you think it might be related though?
