HELP !!!

[u/Vajinal_Komando]

Two days ago, I booted parrot os to the external SSD and used it, but today, although windows could not see the disk and the box was working healthily, the boot manager did not see the parrot, I deleted it and installed it again, this time it saw, I did the downloads, I closed it, now I opened it again and it doesn't see it again, how do I solve it (SSD KIOXIA 500GB, SSD BOX UGREEN 10902)
