Tried installing Fedora alongside Windows 10 - No Operating System Found

Question

So, I installed Fedora on a live USB and tried installing it to my PC. I think I somehow messed up the ESP boot partition and whenever I start my computer it says "no operating system found". I can still access the live USB from my BIOS and when I check my files, they are all still intact. Now, I have two questions:- 1) Is there a way to delete files from my hard drive, it is read-only right now and is it possible to change that? 2)Is there a possibility of creating a recovery image of my Windows partition(C: drive) and back it up to a D: drive or a complete separate harddisk that i have? If there is, how do I proceed after that? What do I do to fix the boot stuff without losing the files in my D: drive which doesn't have the Windows Operating System. Some technical specs:- Running Fedora 28 Workstation Windows 10 OS 1 TB HDD Windows Operating System drive size 60 GB(Could be reduced to around 50 if I could delete files from it) D: drive - 560 GB free space Separate harddisk - 120 GB Edit: Size of live USB running Fedora shows 6.8 GB with 1 GB free but it is actually a 16 GB USB stick.

Answer 1

Your issue stems from the fact that your /dev/sda2 is TOO small for both Windows and Fedora EFI bits.

Some background info:

The average Windows 'kernel' is 75Mb in size and a default 'just works' Fedora kernel is 25-28M, simple math shows 100-105M > 99M.

If I understood your 2)Is there a possibility of creating a recovery image of my Windows partition(C: drive) and back it up to a D: drive or a complete separate hard disk that i have? question correctly you'd need either:

1) enough spare drive space to hold roughly 300Gb to contain ALL of the present Windows and Fedora data.

2) enough space (noticeably smaller restraint) for the non-os data on Windows and Fedora respectively

At which point I'd recommend starting the partitioning logic from scratch with the following minimal partitioning:

---

(Windows ESP/MSR)

/dev/sda1 450M

BOOT/EFI

(Enough for Windows kernel and the default 3 kernels held but grub)

/dev/sda2 100M or better (256M is common)

(Windows ESP/MSR)

/dev/sda3 16M

(Windows C:)

/dev/sda4 116.8G

(Windows D: (possible Shared Drive across both OSes)

(CAUTION: This drive Should NOT be reformatted during reinstall, nor does it need reformatting; unless all precious data is copied/backed up somewhere)

/dev/sda5 661.8G

(Fedora 28 -- Using Default LVM)

/dev/sda6 144.3G

(Fedora Swap)

Should ideally be part of the sda6 lvm

/dev/sda7 8G
