BOOTMGR missing in Windows 10, which is impossible because I've cloned the HDD ENTIRELY to the SSD.

I've tried Macrium Reflect which is currently giving me this issue every time I try booting form the SSD after the cloning process has been completed. So I backed up everything, emptied out the PC and now it has roughly 20GiB left on the machine, which makes the process of cloning the HDD much easier to do and transfer the OS to the SSD. Now, it seems to me that the 1TiB 7200RPM hard drive that came with the PC is showing its death, the PC is slow, it gets stuck constantly, etc.

It may also be worth noting that the drives replaced by the new ssds were dynamic drives and had to be cloned rather than copied.Īs always, all input is enormously appreciated.“My Parent's PC is an HP Touchsmart AIO from like 2010(?) with a 6000 series A8 APU in it. Running windows 10 home, but upgraded a few weeks ago, before the hardware upgrade. New ones as follows: 2x Crucial 2TB SSD, Gigabyte Aorus Wifi Pro, i7-9700k, 1x16GB T-Force Vulcan C ddr4 3200. I can still boot from the older, smaller ssd that I had used for the windows install. Imagine my shock when I turn on my computer again (with only that drive connected) and boot manager is still missing.

I was eventually told to format my original C drive and reinstall Windows onto it, which I did. Had lots of difficulty installing Windows 10 on the C: ssd, or for that matter anywhere else. Looked at the drive through my EaseUS boot able thumb drive, and the format is now Raw. Then tried in the winpe environment for installation of Windows to repair startup, which also didn't work. I've spoken at length with a Microsoft agent and they initially directed me to use bootrec command lines to repair MBR and fix boot - the latter of which did not work (denied access). Then this morning I turned on my computer and it said boot manager is missing. I cloned the old c: (ssd) and everything worked fine. With these changes came the addition of two new ssds, one of which replaced my boot drive. Hi and happy holidays! I recently upgraded large parts of my computer for Black Friday.
