I have an Acer laptop. The original operating system was 8.1 but did take advantage of the free download of 10 when offered. There has been no problems except this morning. Started as usual and got the message "Unmountable boot drive" and system would attempt to fix. No such luck, in poking around for a cure, tried the start and immediately turned off when Acer showed to prompt the computer on 4th try to send me to a starting error. Still got the same boot message and then a blank page. A couple places mention downloading Win 10 media installation on a USB (no CD drive) which will boot and correct? This is where I am fuzzy. Will it erase everything? Does this sound right? Is there another way to correct this issue that is easier and/or safer? Since I am getting a blank page there is no prompt.
