Lenovo laptop using Uefi, with Win 8.1. NOT booting. To use Norton Recovery, on USB flash, set to Legacy boot. Got to choosing latest Recovery backup, on external USB HD. Got message that couldn't recover Uefi to Bios system. Recovery was done Dec 2022, with latest updates. If I do Chkdsk, All ok till gets Read error with Journal $J. Boots with Win 8.1 install, but can't repair or refresh. Takes hour or more to get some of these windows up (Recover, Win 8.1 CD boot, Hirens). Tried Bootrec items. Fixmbr seems to complete. Fix boot says nothing to find. Built-in Onedisk recovery loads files, but NOTHING more. If Norton Recovery flash boots, and I get to Command prompt, can I get to Arecovery on external drive, and will it recover C drive, wifi or bios? C is partition on Tb drive. Part List shows C as "raw". Others as Ntfs. Been trying LOTS of things. Spinrite 8 for example.
