till now my partition was gpt uefi bios but with rufus I had to create with ntfs as iso was 4200mb and I had to select other os in bios instead of uefi now my all partitions are ntfs in ssd I have 3 drives now if I use uefi usb iso will all drives be converted to gpt automaticaaly I have c d and e I will delete and format it so I know it will be gpt but what about d and e? will they work without loss of data
I dont know because your question is hard to answer because there is no punctuation but if you thought about who was going to read it perhaps you could make it easier to read so someone could give you a better answer have you thought about that I wonder
I think if you have UEFI boot, the boot partition must be a GPT partition. But the other partitions can be MBR or GPT.
Hi,
C partition is always ntfs and so are all other partitions except one efi and a fat32 maybe
You'd have to really post a free mini tool disk layout screen shot for better understanding
Disk management often hides some partitions.

Partitions are not MBR or GPT. Physical disks are MBR or GPT. To talk about a partition being GPT or MBR is impossible. To talk about C drive, D drive, E drive, etc being MBR or GPT is impossible. Also, a GPT disk is NOT required to boot in UEFI mode. UEFI can boot from a GPT or MBR disk.
Physical disks are MBR or GPT:
Each disk can have multiple partitions. The partitions are not MBR or GPT. The partitions may contain file systems and drive letters:Code:DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 476 GB 0 B * Disk 1 Online 476 GB 1024 KB *
We have no idea what @tushar4544's system consists of. Is it one physical drive with multiple partitions assigned to multiple drive letters? Is it multiple physical drives? Which physical disks are MBR or GPT? We don't know. We don't have enough information to offer valid advice.Code:DISKPART> select disk 0 Disk 0 is now the selected disk. DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Reserved 16 MB 1024 KB Partition 2 Primary 404 GB 17 MB Partition 3 Primary 64 GB 404 GB Partition 4 Primary 8 GB 468 GB DISKPART> list volume Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- Volume 0 D Data NTFS Partition 404 GB Healthy Volume 1 NTFS Partition 64 GB Healthy Volume 2 R RECOVERY FAT32 Partition 8 GB Healthy Volume 3 C Win10 NTFS Partition 348 GB Healthy Boot Volume 4 E Insider NTFS Partition 128 GB Healthy Volume 5 NTFS Partition 478 MB Healthy Volume 6 FAT32 Partition 100 MB Healthy System
Also, a GPT drive is not a requirement to boot in UEFI mode. UEFI can boot from an MBR or GPT disk. However, to boot in legacy BIOS (CSM) mode, the system drive must be MBR.
Hi,
Yep if D and E disks are really disks and not partitions on the same disk as C is on they should be Removed/ Disconnected to make sure nothing happens during the reinstall.
After reinstall reconnect the other ssd/ hdds and all is well.
hi thnx for replying i made iso with rufus but with ntfs format as fat32 was disabled as iso size was 4200mb so i first had to change bios to OTHER OS instead of UEFI it booted now all my drives on ssd i have one only are NTFS MBR i guess now my question is what is the difference between MBR and GPT as till yesterday i used gpt as iso size was never greater than 4gb till now
Hi,
Post a disk management screen shot at the least.
Your terms in describing the disks involved are confusing.
