Windows 10: I need help: Sister's Laptop has a broken Partition Table

I am in some desperate guidance on how to fix my sister's Toshiba Satellite Laptop. Her partition table is either corrupted or broken. I tried downloading the Minitool Partition software with Rufus to boot from it but each time I boot from it, it says it doesn't have a valid signature and that I need to load some sort of kernel.

I have ordered an SSD for it to make it faster as it was slow prior to the partition table getting messed up.

I really need help ASAP!!

Thanks,

Windows 10 1909

Help, partition table issue!!

Im trying to resize my partition on my laptop to install kubuntu but my partition is corrupted.

it still boots into windows fine but i cant get partition magic to recognize the drive.

i ran partition table doctor 3.0 and it found my old linux partition and didn't recognize my current windows partition, how can i repair this?

right now all i have is one partition as big as the entire drive.
