String of characters Ñ Ñ Ñ Ñ Ñ Ñ Ñ appears at preboot
When " Ñ Ñ Ñ Ñ Ñ Ñ Ñ” appears, usually something is wrong with updating E0.BIN.
Either:
1. The updated E0.BIN is invalid
The client development team probably can help with this. Using which file to update and whether that file is correct.
2. Or the relocation table in MBR Extension for E0.BIN is not pointed to the correct start sector of the updated E0.bin.
The client development team can also help check whether the logic of the update REL is correct.
We can also get a copy of the SD space from that machine to check it. Attach that hard disk to another machine and use some tools like WinHex to examine it
