Hello! It sounds like you're facing a challenging situation with your laptop's corrupted OS and the inaccessible files on One Drive. Here are some steps you can take to address this issue:
1. Backup Important Files: Since you mentioned using Hiren's Boot CD to access some files, try copying the files from your laptop to an external drive or another storage device. This way, you'll have a backup of your important data before formatting your laptop.
2. Recover One Drive Files: If you are unable to access your One Drive files due to full storage, you can try the following steps:
- Check if there are any large files or unnecessary items in your One Drive account that you can delete to free up space.
- Upgrade your One Drive storage plan to accommodate more files if needed.
- Contact Microsoft support for assistance in recovering your files or freeing up space on your One Drive account.
3. Reformatting Laptop: Once you have backed up your important files and resolved the One Drive storage issue, you can proceed with formatting your laptop to address the corrupted OS. Make sure to create a backup of all necessary data before reformatting.
4. Reinstalling OS: After formatting your laptop, reinstall the operating system and restore your backed-up files from the external storage device.
5. Preventative Measures: To avoid similar issues in the future, consider regularly backing up your important files to multiple locations, such as external drives, cloud storage, or a network drive.
If you encounter any difficulties during the process, feel free to seek further assistance from the community or professional IT support. Good luck with resolving the issues on your laptop!
