ThE iNsAnE Posted August 17, 2020 Share Posted August 17, 2020 I had a windows 8 OS installed on my laptop on C drive (Primary). Apart from that I had a D drive(Logical partition) and E drive (Logical) Now on disk management, i could see a system reserved partition which is quite normal. Now i wanted to freshly install windows 10. So i booted up easeus partition master bootable media and deleted the old system reserved and C drive. I left the D drive and E drive alone. Next, i installed windows 10 using a USB on the C drive. Everything went well and still all is fine however, the fresh install of windows 10 did not create a system reserved partition. It installed on the C drive only and the system works fine. Just curious as to why the fresh installation did not create the system reserved partition? Also, should i be worried if it is not there? There should be some purpose of the system reserved which is why it gets created in the first place. Can someone explain as to why this happened?

You should just have a small partition of about 500 MB reserved on your HDD, just for Windows 10 system files, are you sure you don't have this? /EDIT can you check in your disk management, if you have some form of reserved storage, normally 500 MB, but one can make this even smaller for a faster booting Link to comment Share on other sites More sharing options...

Checked in windows in built disk management console as well as easeus partition master screen. Link to comment Share on other sites More sharing options...
appzter Posted August 17, 2020 Share Posted August 17, 2020 Your Win10 install is likely running in Legacy (MBR) mode rather than UEFI mode. Actually, I much prefer Legacy mode (unless your PC's drive is larger than 2TB) as it simplifies backup operations (compared to having to include UEFI's additional EFI/System and MSR partitions in a system backup)!

Expand I don't have much idea about those. However, windows 8 was also running in the same machine. It had a system reserved. During installation of win 10, i just selected the c drive and installed. My computer has a BIOS so it should be in legacy mode only right? Link to comment Share on other sites More sharing options...

appzter Posted August 17, 2020 Share Posted August 17, 2020 Most, if not all PCs have a BIOS. Before installing Win10 you must have been running Win 8.1 in GPT/UEFI mode. When you performed a fresh Win 10 install it sounds like it installed in Legacy mode. Do this: Press the keyboard's Windows and R hotkeys together and type msinfo32 in the Run box. In the System Summary section, look at the BIOS mode value in the right pane. It can have the value 'Legacy' or 'UEFI'. Link to comment Share on other sites More sharing options...

Expand Either installation was performed through legacy or UEFI, a reserved system partition is created during the installation unless you prevent it from being created. i think in his case, he created a new partition that used all unallocated space by using easeus partition master which made the partition active, that's why the reserved system partition wasn't created during the installation. If it's the case (waiting the screen that i asked above), he may have problems when upgrading to recent build so i think it would be wiser to reinstall win10 but this time just through the iso (you will be able remove the partitions and create a new one easily), no need to use a third party tool to remove the partitions. This way the system reserved should be created correctly. Link to comment Share on other sites More sharing options...

During windows 8 time, i was having a recovery partition, system reserved partition and c drive partition. All 3 were primary. Since i wanted to start fresh, i booted easeus patition master, deleted all 3, created a single C drive primary (without any OS ofcourse at that point). Boooted win 10 iso, chose C drive to install and completed the process. I thought system reserved would be created by default in such case. However, oi was not created. I read that system reserved would be useful in case i would like to use bitlocker in C drive. However, as you said, if there is chances of problems in future too, i am worried should i install fresh?

neofita Posted August 18, 2020 Share Posted August 18, 2020 If Windows is installed in Unallocated Space you have the Reserved System Partition, which contains the boot files. if it is installed on a pre-existing partition the boot files are written on the same partition regards Link to comment Share on other sites More sharing options...

I will fire up the iso, again point towards c drive. Will the system reserved be created this time or should i do something else? I don't want to mess with my D drive and E drive.

Expand Yes the System Reserved partition is created automatically but only if you point the Windows installer to a free portion of the disk where it will create the needed partitions, if you select an existent partition it simply formats and use the already allocated space.
